  • Duo works with any mobile phone — a cellphone other than a smartphone or a smartphone without the Duo Mobile app — by supporting authentication via callback and SMS text message

Can you resolve this issue yourself?
Can the end-user resolve the issue using the instructions given?
Or does the end-user need to request assistance from Miami UIT, a client office, or a vendor?
Yes! This is self-service with a smile.
