Bypass Code

If you reach out to IT in advance, we can generate a multiple-use security code that will be valid for the duration of your travels. This code should be stored on your person (e.g.s wallet or purse).

If you have any questions about logging in to Duo or to request a physical token, we can help.  Email us at, or call 7-1111.
