Confirm Registered Devices

After setting up Duo Mobile on your mobile device, it's important to regularly verify all the devices connected to your account. This is a key information security practice, as unfamiliar devices on your account could mean it has been compromised. 

To confirm your account devices, you can follow the steps you used to enroll your smartphone in NetID+:

  1. Go to the 2FA Portal.
  2. Click Manage Your Account and follow any prompts that appear to log in.
  3. Locate the My Devices section.
  4. Confirm that all the listed devices are the ones you recognize.
  5. Use the Settings gear icon (top right of the device card) to remove any unfamiliar devices or devices you are not using.

Immediately perform a Password Reset (NetID) if you notice any unfamiliar devices listed on your account.
