Why Do I Need A PIN?

In combination with the student ID number, PINs permit students to enroll for classes, receive grades, change personal and parents' addresses, emails and phone numbers, accept finacial aid, check Bursar balances and make credit card payments. You must use your PIN to receive your grades on the Web. You may order transcripts and enrollment verification letters.

If you have activated your O-Key account, you may use your email-address and O-Key password to login to SIS. If you have forgotten your O-Key password, follow this link: Forgot Your Password? Create a new one!

How Do I Know What My PIN Is?

As students are added to the SIS database, PINs are automatically set to the student's birthday.  For example, if your birthday is May 31, 1980, then your default PIN is 053180.  Students may login to the SIS Self Service, using their six-digit birthday (MMDDYY).  The first time the PIN is used, the system will require that the PIN be changed from the student's birthday to any six-digit number except the student's birthday.
