How to Add a Second Device to your Duo Account


If you would like to add a secondary device to your Duo MFA account, such as a work phone or tablet, you must always add that device as a Tablet. This is because a phone number is already attached to your Duo account if you have one device on it, so you will not be able to add a second phone number to the account. Make sure that you add secondary phones as Tablets, and that you have Duo Mobile installed on your device prior to beginning this process.
