Why can’t I use my NetID and password everywhere I need to log in?


At UTK, we provide many services to faculty, staff, and students that require one to log in or "authenticate." We work hard to ensure these packages know it is you by standardizing on NetID and password. Unfortunately, there are slightly different approaches among our software vendors, and even when we standardize, there are subtle nuances.

We encourage as many campus services as possible to use our Central Authentication Service (CAS).  This is the sign-in page you see when you log into Canvas, MyUTK, and MyIRiS and only requires NetID, password, and two-factor authentication(2FA). However, our email systems work a little differently.  Microsoft and Google offer cloud-based email, storage, collaboration, and other services to almost anyone who wants them.  To tell Microsoft and Google that you need to log into your UT account, you must use your full email address, either NetID@utk.edu or NetID@vols.utk.edu, and then your NetID password and 2FA.

For some services, like Zoom, you must provide them with enough information to get you to CAS.  Here are some examples:

  • Zoom: Select the Single Sign-On (SSO) option and then enter 'tennessee' before zoom.us.  This tells Zoom that you are using a UT Zoom account, as opposed to a personal account.  Once they have this information, they will send you on to the CAS login page.
  • Adobe: Enter your NetID@tennessee.edu email address when asked for an email address; this tells Adobe to send you to the CAS login page.

We do work hard to help ensure consistency and the integrity of single sign-on. Still, from the brief examples above, you can see differences even though it is ultimately NetID, password, and two-factor authentication(2FA).

Why do some services require tennessee.edu instead of utk.edu? 

The University of Tennessee has several campuses, and we collaborate on a number of software licenses. Like Zoom and Adobe, some require 'tennessee', while other contracts are campus contracts, and they need 'utk'.  Each campus has its own email domain, which is why we use our campus email address (in our case Knoxville-area) instead of a statewide address.

We know it gets complicated!  We have a few suggestions to help you keep it straight. 

  1. When possible, start in MyUTK.  MyUTK has links to several resources such as Canvas, IRIS Pay Statement, Office 365, Google, Zoom, and more.  When you log into MyUTK, we will go ahead and sign you into any services that use CAS. 
  2. Start at the UT information page about the service.  Signing into Linkedin Learning from OIT’s page is a much better experience than navigating the LinkedIn website.  Go to linkedinlearning.utk.edu to get started. 
  3. Search in OIT’s portal at help.utk.edu for step by step instructions: 

Don’t forget to pay attention to what you are asked.  If the field says NetID or Username, it’s most likely requesting your NetID.  If you are prompted to enter your email address, use your UT email address. 

When in doubt, contact the OIT HelpDesk.
