End-to-End encryption is a secure communication system that uses cryptographic keys only available for the sender and receivers of a message
Meta has previously rolled out end-to-end encryption support for messenger calls and chats
Messenger users can store their chats with end-to-end encryption in Meta's secure storage and access the backup data through a PIN or generating by a code
Meta has started testing secure storage on the messenger app for Android and iOS
The company has also started testing default end-to-end encryption for messenger chats for a small group of users
The messenger may soon get an end-to-end encryption feature for its users to maintain their privacy.
