About 2facheck

A calmer way to authenticate.

2facheck is a lightweight, browser-based TOTP generator. It is built for those moments when you have a manual setup secret and need a current authentication code without installing an app.

Simple by design

No sign-in, database, analytics or third-party scripts. The code runs in your browser and follows RFC 6238 and RFC 4226.

Use it thoughtfully

This is a temporary code generator, not a password manager or a recovery service. For everyday use, keep your credentials in a trusted dedicated authenticator. We are not affiliated with the services whose codes you generate.
