All me has selected Proton Authenticator as its primary 2FA authentication app.
Proton Authenticator is an open-source and end-to-end encrypted software-based authenticator. When logging into a website or application that supports multi-factor authentication, the user will be prompted for a six-digit one-time password which changes every thirty seconds. Proton Authenticator displays the current six-digit code, the next six-digit code, and the remaining number of seconds until the current code expires.
Proton Authenticator is available on iOS, Android, macOS, Windows, and Linux.
