How to change the password on your admin or staff account
If you know your current password, and want to change it, start by logging into your administrator account and clicking your name in the upper right hand corner of your screen. Then, select "Edit Profile".
Alternatively, this may also be accessed through the sidebar via "Settings":
Navigate to the "Password" tab. Enter your current password in the "Current Password" box. Enter the new password in both the "New Password" and "Confirm Password" boxes. Click "Save" when finished.
