Facebook-owned WhatsApp is finally rolling out end-to-end encrypted backups for beta testers!

According to WABetaInfo, you need to choose a password that will be used to encrypt your future backups. It’s always needed to insert the password when you restore a backup, otherwise, you won’t be able to restore your chat history. This password is private and it’s not shared with WhatsApp, Facebook, Google, or Apple.

End-to-end encrypted backups also support an encryption key that can be used to restore your password. It can only contain numeric digits and lowercase letters between ‘a’ and ‘f’. If you lose this key, WhatsApp cannot help you to recover it.

The Facebook-owned service is also testing a version of the software that works across multiple devices, maintaining end-to-end encryption whether or not you have a phone involved. If you’re in the beta, check your version carefully, as posts on social media suggest the closed encryption tests are expanding to include more people.
