Messaging app Viber on Wednesday rolled out its new "hidden chats" feature for its 23 million users in the Philippines to boost security in one of the world's social media capitals.

The new option allows users to hide specific chats from the main screen and requires a four digit access PIN, Cyprus-based Viber said in a statement.

The "hidden chats" option is part of the latest version of Viber, which features complete end-to-end encryption across all devices.

The app update also includes increased security across the platform for both group messages and one-to-one communication.

Viber is one of the world’s leading messaging apps with more than 711 million unique users worldwide.
