Use Manage your Duo access to add a verification method or update a device already enrolled with SUNY Plattsburgh.
Before changing devices
Keep a working verification method until your new method is activated and tested. Device management requires you to verify your identity with a method offered on that screen. A method that works for ordinary sign-in may not be available for device management. Do not assume text-message codes or bypass codes will be accepted.
Add another device
- Open Manage your Duo access and select Open Duo device management.
- Sign in with your NetID and complete the verification Duo offers.
- Select Add a device and choose the method you want to enroll. Choose Duo Mobile to connect the app; the separate Phone number option enrolls text-message authentication.
- Complete activation and test a campus sign-in with the new method.
Alternatively, start a MyPlattsburgh sign-in and use Other options → Manage devices when offered.
Replacing a phone
If the old phone already used Duo Mobile, follow the reactivation or I have a new phone option when offered for that device. See Duo's reactivation instructions. If your old phone used only text-message codes, use the SMS-to-Duo-Mobile guide instead. Contact ITS if the number is already registered and you cannot activate the app.
Text-message authentication is being phased out. Choose Duo Mobile or another available campus-approved method. If you cannot use any verification method, contact ITS for identity-verified recovery.
