Phone Authenticator – 2FA is a productivity app designed to enhance account security through Two-Factor Authentication (2FA). This free Android application generates time-based one-time passwords (TOTP) to provide an extra layer of protection beyond traditional passwords. Users can manage multiple accounts, generate secure codes with a simple tap, and utilize a QR code scanner for quick setup. The app also includes optional cloud backup and restore features, ensuring that users can access their codes across devices if needed.

The app operates offline, generating codes locally without requiring unnecessary permissions. TOTP codes refresh every 30 seconds, while HOTP codes are generated based on a counter. Users have full control over their accounts, with the ability to delete accounts and manage access through Google Account settings. With a user-friendly design and trusted encryption, Phone Authenticator ensures that your one-time passwords remain secure and private.
