Frequently Asked Questions (FAQ)

Does Rapid2FA store my secret keys?

Absolutely not. All encryption and calculations are performed via JavaScript directly in your browser. Your data never leaves your device.

Why is my OTP code not working?

TOTP is time-dependent. Ensure your computer's date and time are set to "Update Automatically." Even a 1-minute difference can cause the code to fail.
