FAQ
What is otpauth://?
A URI scheme originally proposed by Google Authenticator that has become a de facto standard supported by most authenticator apps, used to encode TOTP/HOTP account setup information (secret, issuer, algorithm, etc.) into a QR code.
Is the secret sent to a server?
No โ the QR code is generated entirely in your browser, on your own device. The secret is never sent externally.
How do I check the actual generated code?
If you want to see the current 6- or 8-digit one-time password itself, use the separate "TOTP Code Generator" tool.
