Have a new phone? Want to add a security key? You can easily add new devices right from the Duo prompt.

1. Choose an authentication method and complete two-factor authentication to begin adding your new device. If you're adding a new device to replace one that you previously activated for Duo Push, don't select the Duo Push authentication method on this page unless you still have the original device. If you don't have the original device, but you have a new device with the same phone number, then you can authenticate with a phone call or SMS passcode. You can't add a new device from this page if you do not have access to any of your previously enrolled authentication devices; you'll need to contact your Duo administrator for help.
