What if I am traveling abroad?
You have several choices when traveling abroad. Test them prior to traveling so you can verify which solution is best for you.

Why doesn't my phone show a popup from DUO or display a notification?
Different phones handle this differently. Apple phones don't allow the popup, and you have to set notifications for each app appropriately. See DUO's documentation on troubleshooting iOS issues here for more information. You can view similar instructions for Android devices here.

What if I receive a DUO authorization request I did not initiate?
If you receive an authentication request you did not initiate, it may be an indication that someone else is trying to gain access to your account. Deny the request and report it to IT service desk. You should also immediately change your NetID password by visiting http://netid.usf.edu.
