If you have administrator permissions, you can remove a user to your account:
- Sign in to your AdMob account at https://admob.google.com.
- Click Settings in the sidebar.
- Click the Users tab.
- Check the checkbox next to the user you’d like to remove.
- Click Remove.
- In the dialog that appears, click Remove to confirm you want to remove the user.
The user receives a notification email and their details are removed from your users page. When you remove a manager or administrator from your account, they can no longer sign in to your AdMob account.
