FAQ

2FA code generator questions

What is a TOTP 2FA code?

A TOTP code is a time-based one-time password generated from a shared secret and the current time, commonly used by authenticator apps.

Is this the same format as Google Authenticator?

Yes. This tool generates standard 6-digit SHA-1 TOTP codes using a 30-second period, which is the common Google Authenticator-compatible format.

Should I paste real personal 2FA secrets here?

No. Use this tool for QA, demos, and test accounts. Do not paste secrets for important personal, admin, banking, or production accounts.
