Why Easy Auth?

Zero-Knowledge Encryption

Your TOTP secrets are encrypted with your password before leaving your device. We never see your plaintext data.

Cross-Device Sync

Access your 2FA codes anywhere. Encrypted sync across your browser and Chrome extension.

Offline Support

Generate TOTP codes even without internet. Changes sync when you're back online.

Open Source

Full transparency. Review the code, self-host, or contribute improvements.

Security First

Easy Auth uses AES-256-GCM encryption with keys derived from your password using PBKDF2 with 600,000 iterations.

Your encryption password never leaves your device. The server only stores encrypted blobs that are useless without your password.

End-to-end encryption
No password recovery (by design)
OAuth login (no password to steal)
Secure session management
