faq
Where do I find the secret key?
Identity providers usually display the key alongside a QR code during the 2FA setup process.
Why is my code invalid?
TOTP is time-dependent; ensure your device clock is synchronized with a global time server.
Is my secret key stored?
No, all processing is stateless and local; the key is never saved or transmitted from your browser.
