OSU has two systems for students to manage their personal information.  O-Key is actually a password management system that allows students to find their own official OSU username, redirect their OSU student email account and create a master password.  Student Self-Services (aka SIS) is available to students to view their academic information, update personal contact information, view their bursar account balance, etc.  If you have not yet logged in to these systems we recommend that you try.

Go to O-Key(  Follow the instructions on the login page for new users.  You will have to call the Help Desk for an activation code. Their phone number is 405-744-4357 or 877-951-4836 or e-mail them at

After you have successfully completed the O-Key process, then move to SIS.  To login to SIS go to You have two options to login here.  1) You can use the O-Key information that you just found in the O-Key system or 2)  you can use your Student ID# (SSN) and your birth date (MMDDYY) the first time you login.  If you use the second method and it is the first time you have logged in you will get a message that says "Your PIN cannot equal your birth date, you must change it".  That message makes it sound like you have made a mistake, however, it is really telling you that you  need to change you PIN. There is a "Change Your PIN" button somewhere on that same page.  Once you have designated a new PIN you will need to logout and login again.

These systems seem a little confusing especially when you only have to use them a few times a year.  That is why it is a good idea to record your passwords and keep them in a safe place.  The Distance Education office and program/departmental personnel do not have the access necessary to reset any of these systems.  If you have problems with the process, please let us know so we can direct you to the correct source of assistance.
