We then e-mail you a 6-digit code to finish signing in.

If your account is locked and you do not know your password: enter your e-mail address and the 6-digit recovery code the Admin gave you over the phone.

If the e-mail does not arrive, ask your administrator for a one-time sign-in code and type it into the same box — your password stays the same.
