Meta’s Messenger app has had end-to-end encryption since 2016, but now it’s enabled by default. This means you don’t have to decide whether or not to use it.
How to Remove End-to-End Encryption in Messenger | Disable End-to-End Encryption in Messenger
On Wednesday, Meta announced a slew of new Messenger and Facebook chat improvements, including the move to make end-to-end encryption the default setting for chats. The setting applies to all Facebook and Messenger communications, including calls and video calls in addition to text chats. But that wasn’t the only improvement Meta rolled out.
One feature that seems to be really popular these days is the ability to edit messages after they’ve been sent. Now, you can do that on Messenger and Facebook chats for up to 15 minutes after you hit send. And if you’re worried about someone abusing that power, you can report edited messages and Meta can see the previous version (you know, in case someone is bullying you and not just fixing a typo).
It looks like Meta has also increased the amount of time disappearing messages are available before they vanish into thin air. Now, a disappearing message will be available for 24 hours before it’s gone, and there will be a notification underneath the message counting down the time until it disappears, and you’ll get a notification if someone takes a screenshot of the message. (Feels like Snapchat to anyone else?) One thing, disappearing messages are only available in end-to-end encrypted conversations.
