Proton Authenticator Old Versions APK
Proton AG
Proton Authenticator is a standalone two-factor authentication app for generating time-based codes that help protect online accounts. It suits people moving from another authenticator, setting up a new service, or keeping a small collection of codes close at hand. Create a code by scanning a QR code or entering a secret key, then use the rotating six-digit value when an account asks for a second factor. The Android app can also import supported providers, show the next code, and connect to Proton Account sync when you want access across devices.
