If you want to remove access to a Kaisa customer account, and prevent a user from logging in, follow these steps:

1. If you are a master account holder, find the customer in the Accounts tab or by searching for it.

2. Open the Settings tab of the account.

3. Click on the tab Users 

4. Find the user whose access you want to revoke and click Remove user.

Finally, confirm by clicking Yes.

The user is now removed and will not be able to login anymore.

If you have a master/partner account and need to remove a user on that level, please create a ticket, and we will help you.
