Facebook Messenger is rolling out end-to-end encryption (E2EE) to millions more users, with plans to make it the default for everyone by the end of 2023.
E2EE encrypts messages so that only the sender and recipient can read them, not even Facebook itself. This is a major privacy improvement for Messenger users, and it brings the app in line with other popular messaging apps like WhatsApp and Signal.
Facebook has been testing E2EE on Messenger for some time now, but the rollout has been gradual. The company says it is now ready to expand E2EE to more users because it has developed new ways to scale the technology without disrupting people’s expectations of speed and reliability.
