Microsoft Seamless Single Sign-On

Microsoft Seamless Single Sign-On

Do you get tired of entering your password repeatedly? The Division of Information Technology understands! We have a goal to reduce the number of times you must enter your password. The fewer times you need to enter a password, the lower the possibility of entering a password into a fake site. Balancing security measures with your experience online is tough, but we believe we are continually getting better at it.

In May 2021, we rolled out a feature called Seamless Single Sign-On (SSSO). The feature only affects on-campus University devices joined to the TXST domain. SSSO will log you into Microsoft 365 when you log on to your domain-joined Microsoft Windows or Apple workstation. Thus, you will be in Microsoft 365 on your computer without having to log in separately.

See SSSO compatibility by operating system and browser below.

*Requires Internet Explorer version 11 or later. (As of August 17, 2021, Microsoft 365 apps and services  stopped support of IE 11.)
****Microsoft Edge based on Chromium

If you are still being prompted for a password on a university-joined computer when signing on to Microsoft 365, make sure to do the following:

  • Connect to the TXST network (cabled or wireless).
  • Update your web browser to the latest version.
  • Apply any system updates.

Note: You may see inconsistencies in Seamless Single Sign-On as there are countless permutations of system patch levels and operating systems.

As with any system, please ensure the site you are entering your password on is legitimate. If you do not know it is a legitimate site, ask the IT Assistance Center! For example, Microsoft’s login page will always use HTTPS (in the top left of the address bar) and through login.microsoftonline.com. If you see those two things and see university branding on the site, you should be good to go.

We hope you like your evolving online experience!
