This document shows how users can add a new device, update a previous device, or remove a device from Duo’s authentication process.
To add/enroll a new device in Duo, click the settings drop-down menu in the upper right corner of the Duo authentication prompt.
Next, click the Add a new device hyperlink.
Duo will then prompt you for an authentication prompt in which you have to enter in a sent passcode or approve a push notification on a device already enrolled.
If you are changing the device listed and have the same phone number enrolled, do not send a push notification. Instead, have Duo send a passcode, as your phone number will be the same but the device that would get a push notification is different. If you have a different device and a different phone number with no access to the previously enrolled details, you
will have to contact your Duo Administrator for help.
You will then be prompted to choose what device you will be enrolling.
If you are entering in anything other than a mobile phone, see this KB on enrolling with a Hardware Token: Duo Enrollment Process
Afterwards, you will enter the phone number of your device, verify you entered the information correctly, and then click continue.
You will need to install the Duo Mobile App on the new device you are enrolling. Follow the same steps as when you first installed Duo and scan the barcode now listed to enroll your new device.
Your device is now listed as an enrolled device through Duo. You can then proceed to enroll another device or configure your already enrolled devices.
Go to My Settings and Devices by clicking the settings drop-down menu in a Duo authentication prompt in the upper right corner.
Choose the device you would like to rename and select the Settings button to go to Device Options.
Then choose Change Device Name listed underneath the device’s name and information.
Rename your device by selecting the original text and retyping it.
After you have typed a new name, select Save to finalize the devices name. The new name will now be listed in Device Options and when prompted for a Duo authentication.
Defaulting a Device
When you have more than one device enrolled in Duo, you can set a device to be the default when completing a Duo authentication prompt. From the Duo authentication prompt, go to the hyperlink My Settings and Devices under the drop-down menu in the upper right corner.
When in My Settings and Devices, underneath your enrolled device there is a drop bar for Default Device. Click on the drop bar to choose which of your enrolled devices you would like to be your default and click the Save button at the bottom of the prompt.
Underneath the Default Device drop bar, you can choose whether you would like to have your defaulted device sent an automatic push notification instead of choosing between a pass code or push notification. If you selected a new option, make sure to click the Save button at the bottom of the prompt.
Now, when prompted with a Duo authentication, your default device will be suggested to complete the push notification or passcode.Removing a Device
When in a Duo authentication prompt, go to the drop-down menu in the upper right corner and click the hyperlink My Settings and Devices.
Click on the Settings button on the device you would like to remove to go to Device Options.
Then, click on the trash button at the bottom of the drop-down to remove it.
You will then be prompted with a confirmation; click the Remove button to delete the device from Duo.
You should receive a confirmation that the device is removed.
