Add a new device to Duo Multi-Factor Authentication (MFA)

1. Add a New Device

To start enrolling a new device, log into and click Add a new device. If you do not see this link, the organization may not have enabled this function. Contact your Duo administrator to have a new device added.

2. Choose your authentication method

Choose an authentication method and complete multi-factor authentication to begin adding a new device.

If you are 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 cannot 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.
