Few months ago WhatsApp came up with a new update, end-to-end encryption on all devices. And Viber today announces complete end-to-end encryption across all devices including Android™ and iPhone, iPad, Android tablets, PC and Mac desktops. Viber is one of the world’s leading messaging apps with more than 711 million unique users worldwide.


As part of this update, Viber also launches ‘Hidden Chats’ allowing users to hide specific chats from the main screen so no-one but the user knows they exist. These chats can only be accessed using a four digit PIN, providing an additional layer of privacy to users personal communications.


“We take our users’ security and privacy very seriously, and it’s critical to us that they feel confident and protected when using Viber,” said Michael Shmilov, COO of Viber. “Because of this, we have spent a long time working on this latest update to ensure that our users have the most sophisticated security available and maximum control over their communications. We will continue to make this an ongoing priority as digital communication evolves.

Users will automatically be protected by end-to-end encryption in all communications on their smartphone once they have upgraded to the latest version of Viber v6.0 or higher.


Users will see a color-coded lock on the right hand side of the screen specifying the level of security:

  1. Grey Lock: During an end-to-end encrypted conversation and call users will see a grey padlock icon. Tapping on this icon will display a tooltip letting users know that messages sent by the participants are encrypted.
  2. Green Lock: Users also have the option of manually authenticating their contacts by selecting that they are ‘trusted’. This means that the selected contact’s authentication key will be monitored for future changes so users can be certain that they’re talking to the right person at all times.
  3. Red Lock: If there is a problem with the authentication key of a previously trusted user, the padlock will turn red. The breach may simply mean that a user has changed their primary phone. To solve a possible breach state, the participant needs to be re-trusted. Tapping on the red icon will display a tooltip noting that Viber cannot verify this number.


This latest update, along with the ‘Delete’ feature allows users to delete messages on the receiver’s phone even after they’ve sent them and whether the person has seen it or not.

It proves that Viber has increased focus on putting its users in control of their privacy and personal communications.
