...The app enables users to link 2FA tokens for their online accounts, scan QR codes, and generate rotating verification codes that enhance login security across services that support TOTP standards. Built with native Android tooling and following modern design conventions, it integrates with Android’s notifications and system UI while maintaining local encryption of stored secrets so that authentication tokens are never exposed in plaintext outside the device. It also supports backup and encrypted sync with the associated Proton account, helping users recover 2FA codes across devices — a feature that many standalone token generators lack without risking security trade-offs.
