In a significant update, Meta has announced the rollout of default end-to-end encryption for personal messages and calls on Messenger and Facebook.

This means that private chats and calls across Messenger will now be automatically encrypted by default, enhancing privacy and security. The implementation is based on robust cryptographic principles, including the Signal Protocol and Meta’s own Labyrinth Protocol. The encryption ensures that the content of messages and calls remains protected from the sender’s device to the receiver’s device, adding an extra layer of security. Additionally, Meta introduced new features such as message editing within 15 minutes, disappearing messages lasting 24 hours, read receipt control, upgraded photo and video features, and enhancements to voice messaging. The rollout will take several months to complete globally, prompting users to set up recovery methods when their chats are upgraded. The move represents the most significant improvements to Messenger since its launch in 2011.
