Conseils pratiques
For users prioritizing privacy and cross-platform access, Proton Authenticator is a strong choice, especially if they already use other Proton services. It’s best suited for those who value a no-ads, open-source alternative to mainstream authenticators. However, users should be aware that backup and export options are limited, and some may find the interface less intuitive when managing many accounts. Testing the app with a few accounts before full migration is recommended.
