2FA QR Code Generator
Generate TOTP QR codes for Google Authenticator, Authy, 1Password, and other 2FA apps.
What is 2FA QR Code Generator?
Two-factor authentication apps scan an otpauth:// URI, encoded as a QR code, to set up time-based one-time passwords (TOTP, RFC 6238). This tool builds the URI from a service name, account identifier, and Base32 secret — then renders it as a scannable QR code.
Frequently asked questions
Is the secret sent anywhere?▼
The QR rendering uses an external service (api.qrserver.com). For maximum security, use this only with test secrets — for production 2FA setup, use server-side generation.
