Hi Jamshid,

I can't really understand what you are trying to do. Could you try to rephrase your question?
If you're trying to change the administrator password, this is what you do:
- Hover on "Dashboard"
- On the "Members" tab, click "Search Users"
- Click on "admin"
- Click on the "Edit User" button
- Fill "Password" and "Password (Confirm)" fields and click on "Update User"

Hope this helps!
