- What To Do When You Receive An Unexpected DUO Request
Never approve an authentication request from DUO if you have not been attempting to log into a CSUSM or Microsoft resource. Depending on which type of authentication request you chose, these requests may come as push notifications, text messages or phone calls. Do not approve or accept any request for authentication if you did not do something to trigger that request.
If you receive a push notification not in conjunction with a login you initiated, you can report it directly from your mobile phone in the DUO app by selecting 'DENY.'
If you accidentally approved a push notification in either app or if you received an unexpected voice call from DUO, you should report these to the Fac/Staff Helpdesk, or call (760) 750-4790 immediately. In rare cases, this could be someone who is trying to gain access to your account with knowledge of your password.
If it is a one time request and you click ‘DENY,’ then you have stopped that access request. In Duo, click 'DENY' then click 'IT SEEMS FRAUDULENT.'

More Information
- Where do I go to install the app on my Mobile Device?
- Do I need a smartphone to use Duo?
A smartphone is the easiest and most convenient way to use DUO, but If you have no smartphone, your smartphone is too old (iOS 10 and older or Android 5 and older), or you would prefer not to use your personal smartphone with the Duo Mobile app, you may request a hardware token (key fob) to use instead. Please make arrangements to go to the helpdesk to request a key fob. Make sure to bring your campus ID when you come to pick it up.

Options: to use DUO:DUO mobile app: Most of the time, you can safely use the DUO mobile app on a smartphone or tablet. Even if you don’t have cell phone service or a Wi-Fi connection, the app can still generate a passcode. If possible, enroll a secondary device in case your primary device is unavailable. (NOTE: try to avoid taking your device(s) to a high risk country).
Hardware Token: If you are travelling without a smartphone or tablet, take your hardware token with you (unless you are travelling to a sanctioned country)
Generate passcodes: before travelling, generate 10 passcodes using your DUO mobile app so you have a backup option to log into your device. Make sure to keep these codes on your person and never leave them unattended with your device
