Facebook Messenger update sets default end-to-end encryption for chats and calls

Today, Meta has unveiled what it calls "the biggest set of improvements to Messenger since it was first launched in 2011." First and foremost, end-to-end encryption is now a default for private chats and calls on Messenger and Facebook, meaning your secured communication can't be spied on by others — not even by Meta itself, apparently. Once updated, Messenger will ask users to set up a PIN, in case they need to recover messages on a new device later. The global rollout may take a few months to complete, due to the fact that the app has over a billion users.
