When your account is required to enroll in Duo, the next time you use your NetID, you will be prompted to setup Duo and your device(s). Do not exit this screen! You will not be able to log in until you successfully enroll a device. This will interrupt the Duo enrollment process and require you to contact the OTS Technology Support Desk. To prevent this from occurring at an inopportune time, we recommend that you opt-in early.  Here is what you will see when you are set to enroll after logging into a service:

You will be asked to add a device (Duo Mobile is universally recommended).

Follow the prompts depending on the device you wish to add to complete your Duo set up!

Once completed you will be required to log in with Duo.

Every time you add a new device you should receive an email confirming your device enrollment. You will be notified when a new device is added in the future.

Bypass codes can come in handy if you forget your device or cannot have your device in certain locations. To generate a set of codes to use when you are unable to use other Duo authentication methods, select GENERATE RANDOM CODES at the bottom of the Manage Duo page within NetID Management (www.towson.edu/netid).

• Keep the bypass codes in a secure location.
• Each code can be used only once.
• All codes will expire in six months.  

Depending on what devices you have registered to use with Duo will depend on how the Duo prompt will ask you to verify your identity. The Duo mobile is the recommended way to use Duo as is it the most secure and easiest option. 

When you use your NetID to log into a TU service (e.g., M365, PeopleSoft, etc.), your Duo app in your enrolled device will display a code.

Launch the Duo Mobile app, enter the code, select VERIFY and Duo will complete your login.
