In compliance with state requirements and current IT practices, the TTU IT Division began displaying an unauthorized access warning reminder screen whenever a user signs into the domain starting August 25, 2006. The addition is cosmetic/educational in nature and does not have any technical implications. As of November 11, 2008, this message is a mandatory component of the sign-on process for all Windows computers joined to the TTU domain.

Please see Texas Administrative Code §202.75.


You may sign in by clicking OK and entering your TTU credentials.

TIP: To speed up the sign-in process, use the keyboard command Ctrl+Alt+Delete, and then immediately press Enter.
