If your school’s installation of Submitty is configured with database passwords, you’ll see the “Change Password” text and a pencil icon at the bottom of the “About You” panel, and you can change this password through the web interface. Click this pencil and enter a new password.

If you don’t see see this option on your account, it is likely this password is served through a shared central password system used by other servers at your school. In this case, please refer to your course syllabus and/or department or university sysadmin resources to change or reset this password.
