Description
The SMS text messaging login method for Duo has become less secure. In order to protect institutional accounts, we will be disabling Duo SMS text messaging as an authentication method option on Thursday, Dec. 16.
How will I use Duo if you’re removing SMS text messaging?
You can use the phone authentication method Call Me, or the Duo Push authentication method.
Call Me
Click the Call Me button on the Duo Prompt (or type "phone" in the "second password" field if you don't see Duo's interactive prompt) and Duo will call your phone. Answer the call and listen to the instructions to authenticate. The Duo prompt's status bar also tells you how to approve the request over the phone. You do not need to have the Duo mobile app installed to use this option.
Duo Push
The Duo Push method sends a notification to the Duo Mobile app on your smartphone every time you attempt to log into a WCM service from outside of the network (view this video for a demonstration). To use Duo Push, youl need to install the Duo Mobile app on your smartphone.
Your smartphone does not need to be tagged or registered with ITS in order to install the Duo Mobile app.
