Frequently asked questions

Are the tools free? Do I need an account?

No. All tools are free and work without signing up.

Where does my data go?

Nowhere. Processing happens in your browser with JavaScript; no request is sent to the server and nothing is stored. Closing the page clears everything.

Why does the 2FA code match the one on the login screen?

TOTP (RFC 6238) is time-based: the same secret and correct clock produce the same code on any device. If your device clock is wrong, the code will not match.
