Swift2FA helps you generate time-based one-time passwords without sending your secret keys to a server. That makes it useful for people comparing 2FA tools, recovering access workflows, or validating TOTP secrets from QR codes and otpauth links.
What makes Swift2FA different
Private by design
Swift2FA generates TOTP codes in your browser, so your secret keys stay on your device instead of being uploaded to a backend.
Fast when you need it
You can paste a secret key or decode a QR code and get a working 2FA code in seconds without creating an account or installing another app.
Built for compatibility
Swift2FA works with common authenticator setups including Google Authenticator-style TOTP secrets, otpauth URLs, and QR-based onboarding.
Easy to verify
The product experience is intentionally simple so users can understand what is happening: decode, extract, generate, and keep everything local.
