Use your TIU username and password, which you use for TIU email, myTIU, and Moodle. Be sure to leave off @tiu.edu at the end of your username (for example, just zjsmith).
The first time you login, email firstname.lastname@example.org or call (847) 317-4015. You will need to be setup with a username and password. You can change your password when you login the first time.
Make sure you are not using @tiu.edu at the end of your username.
Check to see if you're using your current password and not an old one.
Contact email@example.com or call (847)317-4001 for more assistance.
