You will require both System Admin (Sysadmin) and the Admin user roles on ScholarPack to change a staff member's password.
Go to Admin > Personnel > Staff and either search or scroll to find the staff member from the drop down box. Click on their name in order to access the staff profile.
Once in the staff profile, click on "change password/roles" (located to the right of the staff photo).
Give them a new password and confirm it. Scroll down and click Change for this to take effect.
Pass the information on to the member of staff securely and stress that they must change their password once they log in following these instructions: How do I change my own password in ScholarPack?
