Logging in with Single Sign-On (SSO)


This knowledge base article covers how to log in with Single Sign-on and how Faculty and Staff will use Duo for multi-factor authentication at login.


Single Sign-on (SSO) is how you log in using your NetID to access services and applications provided by Towson University. Logging in one-time provides you access to multiple applications without being prompted multiple times. Single Sign-on is provided by a Microsoft solution.

Steps for Single Sign-On

  1. When prompted, enter your Towson University e-mail address, then click Next.

Note: Some individuals may be prompted to 'Pick an Account'. This allows individuals with multiple accounts to choose the correct one (Faculty/Staff or Student account, or another institution/organization). Carefully select the correct account you want to access.


  1. Enter your TU NetID Password when prompted.

  1. Once you're signed in, you may be asked about staying signed in.
    • Choosing 'Yes' means you will not be prompted to log in again for an extended period of time.
    • Choosing 'No' means that once you close the browser you'll need to log in again the next time you access an application or service.
