You can always change your own password. Only the Administrator user is able to change passwords for other users.
Open the Users Table Maintenance window.
Highlight your user ID by clicking on it in the list.
Choose Change Password from the File menu.
You must then type the old password, followed by the new password. You must confirm the new password to ensure that there have been no spelling mistakes.
Click the OK button and the new password will be set.
As well as changing your password from the Administration Module, you can also change your password when you are logging in to Pinnacle.
