Frequently Asked Questions
What is TOTP?
Time-based One-Time Password (TOTP) is an algorithm that computes a one-time password from a shared secret key and the current time. It is widely used in Google Authenticator and 2FA.
Is my MFA key safe?
Yes. The key decoding and TOTP generation are executed entirely client-side using JavaScript. No keys are ever sent across the network.
