Reactivating Duo MFA on a new cell phone

Use these instructions when you get a new cellphone with the same number so that the new phone works with Duo.

Note that if you get a new cellphone with a different number, the instructions are similar but you'll be adding it as a new device instead of reactivating the old one.

Finally, if you don't have a secondary device in Duo MFA to use (or if you have trouble with these instructions), contact the Solutions Center (719.389.6449, its@coloradocollege.edu) for help.
