WhatsApp already allows you to protect backups saved in a cloud service with end-to-end encryption, a function available to users who have activated it from Settings.
The instant messaging service allows you to activate additional protection for copies saved in Google Drive or iCloud, within the chat settings, where “Backup”. To do this, the user must first connect the corresponding cloud service to his device.
By clicking on “Encrypted End-to-End Backup”, the user will just have to click on the “Continue” button. You will then need to create a 64-digit encryption key or password, which you will need to remember and enter when you need to restore the copy.
It is important to highlight the need to remember the chosen key or password, because if the user loses it or does not remember it, he will lose access to his protected copy in the cloud. It is also important in case you want to change a password or another password.
To continue creating the encrypted backup, all you have to do is press the Done button.
Disable encrypted copies
Just as encrypted backup should be enabled, it can also be disabled. In this case, from the same settings screen, the user can use the password, key, mobile device PIN or even biometric authentication.
If the encrypted copy is disabled, the creation of the backup is also disabled. In order to create a copy, the user still has the option to create an unprotected copy or choose the copy that has end-to-end encryption again.
