5M Auth is a lightweight multi-factor authentication app designed to generate time-based one-time passwords (TOTP) and manage access codes for online accounts and community servers. 5M Auth stores secrets locally and provides QR code setup, optional PIN and biometric protection, and encrypted backups for safe offline use.

Key features

• Time-based one-time passwords (TOTP) compatible with standard authenticator protocols
• QR code scanner for quick account setup
• Local encrypted backup and restore with optional passphrase
• PIN and biometric lock to protect access on the device
• Simple list view with copy and paste for one-time codes

How it works

Set up an account by scanning a QR code or entering a secret key. 5M Auth generates codes locally on your device without transmitting secrets to external servers. Use the generated codes when signing in to supported services to add an extra layer of security.

Security and privacy

All secrets remain on the device. 5M Auth offers optional strong backups and uses device-level protections such as biometrics. Review app permissions before use and keep a secure recovery option for account access.
