# Administrate existing users
To administrate an existing user, select the “Administrate users” tab on top of right part of the window.
The list of all the system users will be shown in the left part of the window.
Select “Show inactivated users” checkbox in the left bottom corner to include inactive users in the list.
Select a user you want to modify from the list. The user’s detail will be displayed in the right part of the window.
## User details modification
User Henry Moray was selected in the example.
Make the changes, click “Update user” and sign.
## User’s password change
It may be necessary to modify user’s password. A typical reason for it is when the account is blocked due to multiple login attempts using an incorrect password.
To change the user password use “Change password” button, that will open the dialog shown below.
Enter the new password, click OK and sign.
After the change, the user with a modified password will be forced to change the password again at the first login.
