Stratum (formerly Authenticator Pro) is a free, open-source two-factor authentication app for Android with a Wear OS companion. It supports TOTP, HOTP, mOTP, Steam, and Yandex codes, with encrypted backups, icons, categories, and offline operation.

Use cases

• generate 2FA codes on Android
• migrate authenticator accounts from Google Authenticator or Authy
• back up and restore two-factor tokens with encryption
• view 2FA codes from a Wear OS watch
• manage one-time passwords offline without internet access

When to choose

• you want a privacy-focused, offline 2FA app with no data lock-in
• you need encrypted backups and easy import/export of tokens
• you want Wear OS support for your authenticator
• you prefer open-source, auditable security software

When to avoid

• you need an iOS or desktop authenticator
• you require cloud-synced 2FA across many devices out of the box
• you need push-based or FIDO2/WebAuthn authentication
