Have you forgotten your username and password?

  • Your username is your Centennial College Student ID number.
  • Your password is your date of birth in the following format (MMDDYY), ex. January 15 1980 = 011580.
  • All students are issued a myCentennial login during registration.

How to change your password:

  • Use the "My Account" link in myCentennial (top left corner of screen).

When you try to login and get a message saying your account has been suspended, what does this mean?

myCentennial has detected repeated login failures over a short period of time for your account. For security reasons, myCentennial will suspend your account for increasing periods of time with each subsequent login failure. Call the Helpdesk at 416-289-5280 to have it reactivated.
