Is Telegram safe to use? Know all about the instant-messaging app

Even though Telegram might seem like an underdog when compared to other messaging apps, like WhatsApp, which is the largest messaging service in the world, it surpassed 500 million monthly active users in January 2021. Launched in 2013 and founded by Russian entrepreneurs Pavel and Nikolai Durov, Telegram is a cloud-based instant-messaging app.

The size limit for sharing files on Telegram is a whopping 1.5 GB. However, when content is stored in the Cloud, it can be accessible across devices and this can be seen as a potential security risk for the data.

Telegram is encrypted, private, secure, and independent, making it a better alternative to Whatsapp, which is owned by data-harvesting Facebook. In 2018, British consulting firm Cambridge Analytica collected millions of Facebook users' data for political advertising, without their consent. This means that your conversations and personal information can be stored on Telegram’s servers and accessed by staff and third parties. And no media or files that you send or receive via Telegram can be deciphered and intercepted by your internet service provider, owners of Wi-Fi routers you connect to, or other third parties.

Telegram’s privacy policy includes information on the personal data it collects from you, how the company stores it, what it’s used for, and who it’s shared with. In fact, Telegram records and stores your IP address, device information, and username changes for up to 12 months. As a public messaging app, Telegram is also required to investigate concerning matters and provide your phone number and IP address to the authorities if legally asked to do so.

You can send private self-destructing messages to other Wickr contacts (text, photo, video, voice). It lets you send anonymous messages so even the Signal server doesn’t know who the sender is.

Extra verification: Signal lets you verify that your conversation is genuinely private. Each Signal conversation has a unique device safety number to verify the security of your messages and calls with certain contacts.

However, Whatsapp IS owned by Facebook, one of the world’s biggest data collectors – a reason to be cautious. For absolute anonymity, use a burner sim when signing up to use messaging apps so you don’t get tracked through your normal phone number.

Telegram FAQ

Telegram is a messaging app with a focus on speed and security, it’s super-fast, simple and free. You can use Telegram on all your devices at the same time — your messages sync seamlessly across any number of your phones, tablets or computers. Telegram has over 500 million monthly active users and is one of the 10 most downloaded apps in the world. With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. Business users and small teams may like the large groups, usernames, desktop apps and powerful file sharing options.

Since Telegram groups can have up to 200,000 members, we support replies, mentions and hashtags that help maintain order and keep communication in large communities efficient. You can appoint admins with advanced tools to help these communities prosper in peace. Public groups can be joined by anyone and are powerful platforms for discussions and collecting feedback. And if you want secrecy, try our device-specific Secret Chats with self-destructing messages, photos, and videos — and lock your app with an additional passcode.

As a result, you can access your messages from several devices at once, including tablets and computers, and share an unlimited number of photos, videos and files (doc, zip, mp3, etc.). Telegram needs less than 100 MB on your device – you can keep all your media in the cloud without deleting things – simply clear your cache to free up space. We also have a Bot API, a platform for developers that allows anyone to easily build specialized tools for Telegram, integrate any services, and even accept payments from users around the world.

Just use your main mobile phone number to log in everywhere, your cloud chats will sync instantly. Pavel supports Telegram financially and ideologically while Nikolai's input is technological. To make Telegram possible, Nikolai developed a unique custom data protocol, which is open, secure and optimized for work with multiple data-centers.

Most of the developers behind Telegram originally come from St. Petersburg, the city famous for its unprecedented number of highly skilled engineers. The Telegram team had to leave Russia due to local IT regulations and has tried a number of locations as its base, including Berlin, London and Singapore. We’re currently happy with Dubai, although are ready to relocate again if local regulations change. While Telegram will introduce monetization in 2021 to pay for the infrastructure and developer salaries, making profits will never be an end-goal for us. Telegram's aim is to create a truly free messenger, with a revolutionary privacy policy. Since taking back our right to privacy was the reason we made Telegram, there wasn't much we had to change.

For example, your cloud chats – so that you can access them from any devices without using third-party backups, or your contacts – so that you can rely on your existing social graph when messaging people on Telegram. If you find sticker sets or bots on Telegram that you think are illegal, please ping us at [email protected] You can also use the 'report' buttons right inside our apps, see this post on our official @ISISwatch channel for details. If you see a bot, channel, or sticker set that is infringing on your copyright, kindly submit a complaint to [email protected] To do this in the places where it is most needed (and to continue distributing Telegram through the App Store and Google Play), we have to process legitimate requests to take down illegal public content (e.g., sticker sets, bots, and channels) within the app. For example, we can take down sticker sets that violate intellectual property rights or porn bots.

User-uploaded stickers sets, channels, and bots by third-party developers are not part of the core Telegram UI. For example, if criticizing the government is illegal in some country, Telegram won't be a part of such politically motivated censorship.

If you think we banned your bot, channel, or sticker set for no apparent reasons, drop us a line at [email protected] The relevant decryption keys are split into parts and are never kept in the same place as the data they protect.

As a result, several court orders from different jurisdictions are required to force us to give up any data. Thanks to this structure, we can ensure that no single government or block of like-minded countries can intrude on people's privacy and freedom of expression. Telegram can be forced to give up data only if an issue is grave and universal enough to pass the scrutiny of several different legal systems around the world.

To this day, we have disclosed 0 bytes of user data to third parties, including governments. Another way of contacting people is to type their Telegram username into the search field – you don't need to know their phone number to do this. Try sending them a download link via any other messaging service: email, Facebook, WhatsApp, an actual telegram — you name it.

Android: Open the app menu (swipe right in chat list) > Invite Friends. You can give your friends a link with your username so that they can easily find you on Telegram even if they don't have your phone number.

One check — message delivered to the Telegram cloud and your friend has been notified if he allows notifications. People Nearby is an optional feature that allows Telegram users to explore local groups, find friends to chat with in their area, or quickly exchange contacts with people who are close. Note: People Nearby is never turned on by default – users must manually enable it.

You can also choose to permanently add your profile to the list of nearby people by tapping Make Myself Visible. After becoming visible, you can remove your profile from the list at any time by tapping Stop Showing Me. To protect user privacy, 'People Nearby' always shows distances to approximate locations. As a result, users no longer need to worry about the data accumulating in their chats over the years. Voice Chats add a live layer of ephemeral talk to the group. Easily trace a conversation and keep communication efficient, no matter the group size.

Set default permissions to restrict all members from posting specific kinds of content. Or even restrict members from sending messages altogether – and let the admins chat amongst themselves while everybody else is watching. Send and receive files of any type, up to 2 GB in size each, access them instantly on your other devices.

This way, anybody can view the group's entire chat history and join to post messages. Telegram groups are ideal for sharing stuff with friends and family or collaboration in small teams. You can make any group public, toggle persistent history to control whether or not new members have access to earlier messages and appoint administrators with granular privileges. You can also pin important messages to the top of the screen so that all members can see them, including those who have just joined.

iOS: Start a new message (tap the icon in the top right corner in Chats) > 'New Group'. Android: Tap the circular pencil icon in the chat list > 'New Group'. Telegram Desktop: Click the menu button in the top left corner > 'New Group'. You can add administrators to help you manage your group and define their privileges with granular precision. Android: Go to Group Info (tap the name in the header) > the pencil icon (in the top right corner) > Administrators. It is easy to migrate existing groups to Telegram by sending people an invite link.

You can share username links with friends, write them on business cards or put them up on your website. We are based on the MTProto protocol (see description and advanced FAQ), built upon time-tested algorithms to make security compatible with high-speed delivery and reliability on weak connections.

Telegram’s special secret chats use end-to-end encryption, leave no trace on our servers, support self-destructing messages and don’t allow forwarding. On top of this, secret chats are not part of the Telegram cloud and can only be accessed on their devices of origin. Telegram is open, anyone can check our source code, protocol and API, see how everything works and make an informed decision.

Telegram supports verifiable builds, which allow experts to independently verify that our code published on GitHub is the exact same code that is used to build the apps you download from App Store or Google Play. On top of that, Telegram's primary focus is not to bring a profit, so commercial interests will never interfere with our mission. All submissions which result in a change of code or configuration are eligible for bounties, ranging from $100 to $100,000 or more, depending on the severity of the issue.

This means that all data (including media and files) that you send and receive via Telegram cannot be deciphered when intercepted by your internet service provider, owners of Wi-Fi routers you connect to, or other third parties. Or from any other people that get physical or root access to your phones or computers running Telegram.

If you have reasons to worry about your personal security, we strongly recommend using only Secret Chats in official or at least verifiable open-source apps for sensitive information, preferably with a self-destruct timer. Logging in with an SMS code is an industry standard in messaging, but if you're looking for more security or have reasons to doubt your mobile carrier or government, we recommend protecting your cloud chats with an additional password. You can also set up a recovery email address that will help regain access, should you forget your password.

If you do so, please remember that it's important that the recovery email account is also protected with a strong password and 2-Step Verification when possible. You can order your messages, photos, videos and files to self-destruct in a set amount of time after they have been read or opened by the recipient. To set the timer, simply tap the clock icon (in the input field on iOS, top bar on Android), and then choose the desired time limit. The clock starts ticking the moment the message is displayed on the recipient's screen (gets two check marks). Unfortunately, there is no bulletproof way of detecting screenshots on certain systems (most notably, some Android and Windows Phone devices). After all, nobody can stop a person from taking a picture of their screen with a different device or an old school camera.

After the secure end-to-end connection has been established, we generate a picture that visualizes the encryption key for your chat. Always compare visualizations using a channel that is known to be secure — it's safest if you do this in person, in an offline meeting with the conversation partner. The problem of restoring access to your chat history on a newly connected device (e.g. when you lose your phone) does not have an elegant solution in the end-to-end encryption paradigm. Other apps ignore the need for backups altogether and leave their users vulnerable to data loss.

Meanwhile, the separate entity of Secret Chats gives you full control over the data you do not want to be stored. We are convinced that the separation of conversations into Cloud and Secret chats represents the most secure solution currently possible for a massively popular messaging application. On Telegram, you can send messages in private chats and groups without making your phone number visible.

By default, your number is only visible to people who you've added to your address book as contacts. Note that people will always see your number if they know it already and saved it in their address book.

You may create another Telegram account on the second number as well, for example, if you want to keep work and personal chats separated. Android, Telegram Desktop: Go to Settings > … (in the top right corner) > Log out. Note that logging out does not trigger remote deletion of your secret chat messages on your partner's device — to do that, choose 'Clear History' first. All groups and channels that you've created are orphaned and left without a creator but admins retain their rights. As was just mentioned above, all your data will be flushed from our system: all messages, groups, and contacts associated with your account will be deleted. This means we can't help you unless you have access either to the phone number or to Telegram itself on any of your devices.

First and foremost, you need to contact your phone provider, so that they block your old SIM and issue a new one with your number. Wait till you receive your new SIM with the old number, log in to Telegram, then go to Settings > Devices (or Privacy & Security > Active Sessions) and terminate your Telegram session on the old device.

Common thieves usually throw out the SIM card immediately (the phone is harder to locate this way), then wipe the devices and sell them, so there isn't much risk for the data in case of regular petty theft. Note that inactive Telegram accounts self-destruct automatically after a period of time — 6 months being the default setting.

They can't access your last seen status and don't see your phone number (unless you decide to give it to them yourself). Naturally, any bot should be treated as a stranger — don't give them your passwords, Telegram codes or bank account numbers, even if they ask nicely.

In this case, you'll see 'has no access to messages' in the group members list next to the bot. Some bots need more information to work, so developers may disable the privacy mode.

As for Secret Chats, you don’t need the server-side code to check their integrity – the point of end-to-end encryption is that it must be solid regardless of how the servers function. In a post on his channel, Pavel Durov explained why Telegram hasn't published the server code, even as a publicity stunt.

The encryption and API used on Telegram's servers are fully documented and open for review by security experts. To enable you to run your own Telegram server while retaining both speed and security is a task in itself. Don't forget about our Bot API that lets you build cool stuff on our platform. Both started out as unofficial applications by two different developers and vary in design and functionality.

Telegram for macOS supports many platform-specific features, such as the MacBook Pro Touch Bar, gesture navigation, integration with the Mac's Share menu and more. Telegram Lite is a lightning-fast app, optimized for work-related tasks and handling large communities. It offers a three-column interface, perfect for multitasking and quick access to media, files and links shared in your chats. Telegram is officially available in English, Spanish, German, Dutch, Italian, French, Arabic, Portuguese, Korean, Malay, Russian and Ukrainian on most platforms, and we are gradually expanding the list of languages built into the apps.

If you're looking to go beyond suggestions for individual phrases and would like to help us maintain the official translation to your language on a continuous basis, you can contact @TelegramAuditions. Please include a hashtag with the English name of your language (e.g. #Albanian) and a few links to phrases on this platform with your translation suggestions or comments.

If you would be interested in answering questions about Telegram to users from your country, contact our auditions account. Telegram Passport is a unified authorization method for services that require personal identification.

With Telegram Passport, you can upload your documents once, then instantly share your data with services that require real-world ID (finance, ICOs, etc. Your identity documents and personal data will be stored in the Telegram cloud using End-to-End Encryption.

If you're a developer or owner of a service that requires real-life ID, kindly take a look at this manual. If the tips below don't help, check out this detailed guide on Troubleshooting Notification Issues.

Check notification priority for Telegram in Android settings, it can be called Importance or Behaviour depending on your device. If your phone uses some battery saving software, make sure that Telegram is whitelisted in that application.

For our notifications to work, you need to add Telegram to allowed apps in those devices' security settings. Force quit the app (double tap home button, then swipe up on Telegram), then relaunch and check if it helped. To delete a contact, open a chat with the person, tap the title in the top area of the chat screen to open their profile, then tap on (⋮) in the top right corner > 'Delete contact'.

This means that if you randomly contact people you don't know and send them annoying messages, you may lose the ability to do so in the future. Permission monitors on Samsung and Xiaomi can inadvertently flag and notify you that Telegram requested access to camera in the background.

Anyone can check Telegram’s open source code and confirm that the app is not doing anything behind their back. We also offer reproducible builds that can help you prove that the version you downloaded from App Store or Google Play is built from the exact same source code we publish. Don't be afraid to DM it the number you use for Telegram, we need this info to investigate issues.

If You Use WhatsApp Or Telegram On PC, Your Account Can Be

If You Use WhatsApp Or Telegram On PC, Your Account Can Be

The company said it discovered the vulnerability a week ago on March 7, which it then reported to both WhatsApp and Telegram, waiting for them to finish patching it before releasing the news. Once the user clicks to open the image on WhatsApp Web, the malicious file gives the hacker access to your device’s local storage, where your account data is stored. On Telegram Web, users have to open the image in a new tab for the attacker to gain entry, though from there onwards it’s just as easy to access as WhatsApp. “This means that attackers could potentially download your photos and or post them online, send messages on your behalf, demand ransom, and even take over your friends’ accounts.”. In addition, with your account in hand, the hacker can now also attempt to widen his reach by sending out the same photo to your contacts, who will automatically trust a file sent by a friend.

How Not to Get Hacked on Telegram

How Not to Get Hacked on Telegram

The lightweight chat client Telegram is one of the most common methods of communication in crypto, and there’s a good reason for that. And once the attacker has your number in hand, they can cause all sorts of mayhem, most notably by obtaining two-factor authentication (2FA) codes for your important logins that are sent over text. A lot of tradfi banks and other services operate on legacy technology, for example, meaning that many only offer 2FA authentication via text.

Telegram’s killer feature is that it allows an easy and convenient way to communicate with others via username, instead of phone number. So goes the logic, and so a lot of crypto users just install Telegram, ignore the settings, and call it a day. The primary login method uses a one-time code sent by text, so Telegram lets you set a password as the second factor. To do so, on the Privacy and Security tab, select Two-Step Verification (Telegram’s term for 2FA), and set a strong combination. In essence, that means submitting a request to remove your account completely, after which you will have to wait seven days. So as not to share unnecessary details with all 500 million Telegram users, you need to configure your profile privacy appropriately.

The Telegram application does show that users can prevent IP addresses from being compromised by changing settings. With this setup, the user will need to make a voice call through the Telegram server, although the IP address is hidden but at the expense of audio quality degradation.

Is the Telegram Messenger app safe? -- Parent guide

Is the Telegram Messenger app safe? -- Parent guide

Telegram, launched in 2013, is a messaging app similar to Whatsapp and Facebook Messenger. In October 2021, it saw a surge in users and continues to grow as people move away apps owned by larger companies to stay safe online.

Users can send files of any type, make video calls and participate in group chats. To use the Telegram app safely, users can enable encryption and disappearing messages.

Users sign up with their mobile numbers quickly and easily to access all of the app’s features. Telegram prides itself on its security features, which include options for messages between users to be encrypted or disappear after a certain amount of time. Users can set who is allowed to add them to a group chat, which can hold up to 200,000 different people. Users can protect their Telegram account and app with a passcode set and only known by them. Users can set a password that is required when they log in on a new device in addition to a code sent through an SMS text message. Millions of people use Telegram as an alternative to other messaging apps owned by larger companies.

It doesn’t share users’ information with third parties and it is very easy to use with a clean look, high quality video calls and group chat functions. While many praise Telegram’s security features compared to other big apps, users are still required to sign up using a mobile phone number.

Be Careful Using Bots on Telegram

Be Careful Using Bots on Telegram

One is that the app is a go-to encrypted communication tool for hundreds of millions of users around the world, particularly those looking to duck government surveillance and censorship in countries like Russia and Iran. As a result, adding a bot to a chat or channel undermines its security, potentially making it easier for a third party to intercept messages.

TLS is great for a lot of things but isn't robust enough to act as the only encryption in a secure communication service meant to provide advanced protection. The researchers probed a sample of remote management malware dubbed GoodSender and identified the mechanism within the code that awaited commands from a Telegram bot. Armed with these details, the researchers realized that they could craft API requests that would essentially replay all the communications between the malware author and his bot.
