About this tool
TOTP QR Code Generator builds a standards-compliant otpauth:// URI from your label, secret, issuer, digits, algorithm, and period, then renders it as a scannable QR code you can download as a PNG. Scanning it with Google Authenticator, 1Password, or any TOTP app imports the account instantly — no manual secret typing.
The URI and QR are generated locally in your browser. Your secret is never uploaded or stored anywhere.
How to use
- Enter the account label, secret (Base32), and issuer.
- Set digits, algorithm, and period to match the service.
- Click generate to render the QR code.
- Scan it with your authenticator app or download the PNG.
