End-to-end encryption means that messages are encrypted once sent and then unblocked when they arrive at their destination. They can therefore only be seen by the person who sends them and the person who receives them.
The Facebook group, now called Meta, already owns WhatsApp, a messaging app that uses this technology by default.
The company had signaled its intention to unify its various messaging systems, starting with the Messenger application and direct messages (direct message, DM) of the Instagram social network. These were merged in 2020, and WhatsApp was to follow in 2022, according to a blog post from the giant.
Messenger and Instagram already offer end-to-end encryption, which can be manually enabled in app settings. Users, as well as privacy activists, are calling for the feature to be enabled by default, as is already the case for WhatsApp.
The company weighed on the brakes amid concerns raised about the safety of internet users, Antigone Davis, head of security at Meta, told the British daily. The Telegraph.
Meta does not wish to reduce its ability to help authorities uncover criminal activity on its platforms.
Internet users who were waiting for end-to-end encryption to be implemented on Facebook and Instagram messengers will have to wait until 2023.
