Starting today, millions more people’s chats on Messenger will be upgraded to stronger encryption standards as part of our ongoing end-to-end encryption (E2EE) testing. We remain on track to launch default E2EE for one-to-one friends and family chats on Messenger by the end of the year. And as we increase the scale of testing, we wanted to provide an update on how we’ve approached this large and complex engineering challenge.
Since 2019, a team of Meta’s engineers, cryptographers, designers and policy experts have been working on the challenge of bringing additional encryption to Messenger and Instagram DMs.
However, it quickly became apparent that transitioning our services to E2EE would be an incredibly complex and challenging engineering puzzle. We would have to rewrite almost the entire messaging and calling code base from scratch.
