Duo Multi-Factor Authentication

It could mean your login information is compromised and someone is trying to access your account. Click "DENY" in the prompt or ignore it, then contact the OTS Tech Support Desk. 

You can use the Duo mobile app (available for smartphone or tablet) to generate passcodes even if you don't have an Internet, Wi-Fi, or a cellular connection.

The most common reason for your account to be locked out is from multiple incorrect NetID password attempts or multiple failed Duo login attempts in a row. Wait 10 minutes for your NetID and your Duo access to both automatically unlock. 

You can select the "Remember Me" option. This allows Duo to remember you, lessening the number of prompts you receive. You must be authenticating on the same (non-public) computer/browser and must not clear browser cookies. Learn more.

No smartphone, no problem. You can use the Duo mobile app on a tablet, receive codes to a phone that can use text SMS, use your own security key or pre-printed passcodes.

It’s strongly recommended that you enroll multiple devices when registering for Duo so you can have a backup ready. 

Yes, the Duo mobile app is free. The Apple App Store requires payment information on record even when downloading a free app.

Students using Duo on a mobile device or with pre-printed passcodes (bypass codes) should only add 5-10 seconds to classroom time. If students don’t use technology (laptops, etc.) that require logins, they won’t need to authenticate with Duo. Additionally, Duo isn’t an excuse for students to use phones during class.

Students should use pre-printed passcodes. In your syllabus or at the start of the semester, you can ask students to print these out and bring them to every class. Here's example text that might be helpful to include:

• Be prepared to log into Duo MFA to access class activities (i.e., exams, quizzes) and apps like your Microsoft account, or potentially risk losing points. Set a backup plan at towson.edu/netid in case your primary device is unavailable, and print passcodes in advance.
• Failure to have your MFA device or a backup (lost, was stolen, dead battery, etc.) or printed codes is not an excused absence or a valid reason for make-up work.
• Limit use of devices in class: use your mobile device to authenticate/login, then put it away during class.

Students should use pre-printed passcodes. If the student has set up their security questions in advance, they can request a temporary passcode online at towson.edu/netid or they can call the OTS Tech Support Desk at 410-704-5151 to verify their identity and receive a temporary one-time passcode. Students with the pre-printed codes might avoid lost quiz/exam time. 

If the student is using their own device and checked the “Remember Me” option, they might be able to restart their computer and re-authenticate with their NetID/password without being prompted for Duo (i.e., not need to use their smart device).

If the student did not click the “Remember Me” box, is using a shared device, or their browser settings weren’t saved, they’ll need to log back in with their NetID/password and authenticate with MFA-Duo which will require briefly using their smartphone. Use of a proctor assisting with this process is recommended during testing time.
