Your username is your Net ID. You can locate your Net ID by logging into Banner Web, clicking on "Personal Information", and clicking on "View IDs". Your password should be the same as your student email password and network login password. If you are having trouble logging in it would be a good idea to verify that you have the correct username and reset the password, if necessary.
To do this, visit http://password.gfcmsu.edu and enter your last name, Banner ID, Banner pin, and click the Sign In button. Once logged in, you should see one or two checkboxes. Leave all boxes checked and enter your new password. This password must be 8-20 characters, include both letters and numbers, include a special character such as ! or ?, and must not contain your name or username.
