WhatsApp is reportedly working to increase the security of its cloud backups with a new password protection feature that’ll encrypt chat backups, making them accessible only to the user. WABetaInfo reported on the work-in-progress feature last year, and today it shared screenshots of how it could be presented in the service’s iOS and Android apps.
“To prevent unauthorized access to your iCloud Drive backup, you can set a password that will be used to encrypt future backups,” one of the screenshots reads. “This password will be required when you restore from the backup.” The app then asks the user to confirm their phone number, and select a password that’s at least eight characters long. Another screenshot warns that “WhatsApp will not be able to help recover forgotten passwords.”
Encrypting the backups with a password only you know would theoretically prevent anyone from accessing your chat history without your authorization.
