When you cannot sign in
If a passkey is unavailable on this device, try another device that has your saved passkey, or use your password with an enrolled authenticator when available.
If you have forgotten your password, use the password reset option on the sign-in page and follow the verification instructions shown.
If you cannot use any saved sign-in method, ask DHRU support for help. Describe what you see and the steps you have already tried. Do not include passwords, verification codes or private keys.
