If you use Duo Security for Multifactor Authentication (MFA) to access JLSE or CELS resources, you occasionally may need to change or add a device. Adding multiple methods of authentication is important, so that you’re able to add new devices in situations when your original device may be no longer in your possession.
To start, visit https://dag.cels.anl.gov and enter your Argonne login credentials on that screen. You’ll be prompted to initiate a “Duo Push” or enter a code. However, on the left side of the screen is another menu, including “Add a new device” and “My Settings & Devices”. Selecting either of those will allow you to add more authentication devices to your account.
Note, Duo Federal (our provider for this service) does not allow SMS-based authentication, so adding a second device, if you have one, is a good way to ensure you don’t get locked out of your account.
If you are unable to login due to no longer possessing your registered device, contact the CELS Service Desk at email@example.com or 630-252-6813.
