You can revoke product licenses from end users at any time. Once you do that, the users won't be able to use the product anymore.
To revoke a license
- Log in to your JetBrains Account with organization or team administrator permissions.
In the menu on the left, click on the name of your organization or team.
You will see a list of all product licenses that belong to your company or team. Locate the relevant product name in the list, and click Active subscriptions under it.
- Check the boxes next to the licenses you want to revoke and click Manage at the top. Then select Revoke x licenses from users.
In the dialog that pops up, click Revoke x licenses to confirm.
All selected licenses are revoked immediately. The users won't be able to use the products until you assign a valid license to them.
