- However, you may need to send yourself a one-time passcode to your "text-enabled phone" or "non-university email" that is on file with UWL in order to log into the Duo Device Management Portal. Information on how to send yourself a one-time passcode can be found in the KB article Duo - One-Time Passcode or Bypass Code.
- *Note: Students can update or change their text-enabled phone and/or non-university email with Records and Registration while Faculty/Staff can update that same information with Human Resources.
