2FA code generator
Paste a TOTP secret from Google Authenticator, Authy or any app that uses the standard 30 second, 6 digit, SHA-1 codes. Codes refresh by themselves.
🔒 Private by design. Secrets and codes are computed in your browser with WebCrypto. Nothing is sent to Lot Lane or anywhere else.
Tips
- Only paste secrets you already own. Don't share them.
- Each code is valid for about 30 seconds; the bar shows the time left.
- Works offline after the page loads. No account needed.
