ProSecure Unified Threat Management UTM10 or UTM25 Reference Manual
Note: The one-time passcode is time synchronized to the authentication server so that
the OTP can only be used once and must be used before the expiration time. If
a user does not use this passcode before it is expired, the user must go through
the request process again to generate a new OTP.
3. The user then proceeds to the Two-Factor Authentication login page and enters the generated
one-time passcode as the login password.
