The Duo authentication screen will text 10 single use passcodes to your cell phone. You may choose to write down your passcodes for use when you are not near your phone. If you do please keep these codes in a secure location.
Note: Students have access to Duo SOS to generate a one-time emergency passcode to use when all other forms of authentication are unavailable or not working. The emergency passcodes should be put in the passcode field in Duo Security.
