Reactivating a Device for DUO

If you have issues using DUO on a device (mobile phone, tablet), you might need to reactivate the device with DUO.

If a device you previously added to your Duo account isn't authenticating correctly (either online or offline), reactivate DUO Mobile for that device.  

Why does this happen? Getting a new phone may trigger this issue even if data and apps were transferred over from the old phone.
