How to change the administrator password
The default admin user has full permissions and cannot be deleted. For these reasons, change the admin password as soon as possible.
The admin user in the Matrix is similar to the "root" user in other products.
To change the administrator password:
1. Starting in the dashboard, click System.
2. Click Authentication.
3. Click the Users tab.
4. Search for and click the admin user to select it.
5. In the menu bar, click Edit.
The Edit admin dialog box appears.
6. In the Set Password box, type a password.
7. In the Confirm Password box, re-type the same password.
8. Click OK.
 
You successfully changed the administrator password.
