Simply put, default end-to-end encryption means your 1-on-1 and group chats and private Viber calls can only be read and heard by you. Unlike on other apps, you don’t have to actively enable end-to-end encryption on Viber, it is automatic, which will never change.

Here you’ll find important options such as ‘Hidden Chats’, personal data management, message requests, trusted contacts, and more. We know that sometimes people add you to some “interesting” group chats on Viber, whether it’s your neighbor or someone at work.

Now, you have the power to decide who adds you to group chats – whether it’s everyone or just saved contacts, it’s only three taps away:. Sometimes more than one person uses a desktop computer, but it doesn’t mean you have to share your Viber account with others. Accessed by PIN code only and kept in a different section of Viber, here you have the ultimate private chat. Viber will never ask for personal details, including credit card information or your authentication code in a chat. Sometimes, you get messages from unsaved contacts and if they contain links, phone numbers, or email addresses, they may be harmful. Always know your account is protected by enabling a 6-digit PIN code that you’ll need to enter when registering a new device on Viber.

Communities are a fun and safe space where you can connect with people from all over the world and stay-up-to-date on anything from the news, your favorite sports teams, or celebrities. Community and group chat invitations from unsaved contacts will automatically be filtered in a Message Requests Inbox, so you have more control over what is in your main chatlist.

Stay tuned as more security and privacy options are added to the app – we always strive to make Viber the best for you and are always looking for new ways to improve your experience.
