Overview of Central Login

Some university websites use Central Login to handle authentication.

What is Central Login?

Central Login is a “single sign-on” authentication service used by some Illinois State University websites.

When you visit a site that uses Central Login, you will see a button that says, “Sign in using Central Login”. To log in using Central Login, do the following:

  1. Click the button that says, [Sign in using Central Login].
  2. Enter your ULID and password.
  3. Click [Sign in].

You are now logged in to Central Login.

What if I Type My Password Incorrectly?

If you attempt to log into your ULID account with an incorrect password, your account will be locked for 15 minutes after the 5th consecutive attempt.

Central Login Works on Multiple Sites at Once

Once you are logged in to Central Login on one site, you have access to all sites that use Central Login (without needing to log in again).

For example, if you log in to (which uses Central Login) and then go to iPeople (which also uses Central Login), you will automatically have access without logging in again.

Logging Out of Central Login

When you log out of a site that uses Central Login, you may not be automatically logged out of any other sites you’ve accessed through Central Login. You should log out of each site separately.

After logging out of a site that uses Central Login, you may be prompted to log in again when visiting another site that uses Central Login.

Best Practice: Close All Browser Windows

To be sure you have completely logged out of all websites, you should close all browser windows when you are done and before you walk away from the computer. This is the “best practice” for logging out of websites.

Please note that closing a tab in your browser is not the same as closing your browser window itself. You must close all browser windows (not just tabs). For example, if you have three Firefox windows open, you must close all three Firefox windows to ensure that you have been completely logged out.
