Using your Duo Two-Step Token


Tokens are a small hardware device (pictured below) that generates passcodes on demand to use with the Duo two-step login. You can pick one up at the ITS Service Desk at AP&M 1313 Monday-Friday 8 a.m. - 4:30 p.m. or request one shipped to you by contacting the ITS Service Desk. Upon contacting the Service Desk, you will be asked to set up a time for a virtual ID Verification via Zoom.
