What is Two-Factor Authentication (2FA)?
Two-Factor Authentication (2FA) adds a critical second layer of security beyond your password. After entering your password, you also provide a Time-based One-Time Password (TOTP) — a 6‑digit code that refreshes every 30 seconds and is generated from a secret key stored only on your device. Even if an attacker steals your password, they cannot log in without physical access to your authenticator app or security key.
This tool lets you:
- ▸Verify — paste a 2FA secret or otpauth:// URI to instantly see the current 6‑digit token
- ▸Generate — create a brand-new cryptographically-random 2FA secret with a QR code ready for any authenticator app
- ▸100% Local — all cryptography runs in your browser via the Web Crypto API; no secrets are ever transmitted, stored, or logged
