Meta plans default end-to-end encryption for Messenger by year-end, expanding tests to more users' chats
In response to privacy concerns, Meta aims to secure Messenger with end-to-end encryption for all messages.
Meta previously introduced optional encryption modes for Messenger features like calls and group chats.
A recent incident involving handing DMs to authorities sparked pressure for more robust user privacy measures.
Meta will follow the Messenger rollout with end-to-end encryption for Instagram DMs, addressing engineering challenges.
Despite challenges, Meta's efforts involve rebuilding features and learning from WhatsApp's encryption implementation.
