How do I add a new device or new number to Duo Mobile?

If you get a new phone, but you're keeping the same phone number, it's easy to re-activate Duo Mobile by following these steps. 

If you get a new phone number or want to add a tablet, iPad, etc., however, the process is a little different. For example, a student studying abroad might get a new phone with a different SIM card or a Bucknell employee might want to add a new phone number to provide a different option for authentication.

NOTE: You must have your smartphone and your computer to complete these instructions. Some steps require a computer and some steps require a smartphone.
