# License Keys

Your Online CMS Editor license key is included in the receipt email sent after purchase by Creem. Keep this receipt somewhere safe, as it is the easiest way to find your license key later.

## Find your license key

If you lose your license key, try these options in order:

1. Search your email for the original Creem receipt.
2. Sign in to the [Creem customer portal](https://www.creem.io/my-orders/login) using the email address you used when purchasing.
3. Open your Online CMS Editor installation and check the license details there.

The Online CMS Editor can also take you to the Creem customer portal directly. Open **Workspace > License** and click **Billing and Receipts** to manage your order, receipts, and license information.

{% hint style="info" %}
Creem sends customer portal access by email. If you request a portal link, check the same inbox you used for the original purchase.
{% endhint %}

## Domain coverage

Each license key can be active on one top-level domain at a time. A Free or Solo license only covers a single top level domain, for example:

* `mydomain.com`

**The Studio license covers all subdomains for the same top-level domain.** For example, one Studio license key would covers all of these domains:

* `mydomain.com`
* `blog.mydomain.com`
* `deep.blog.mydomain.com`

You do not need a separate license key for each subdomain. If you want to use the same license key on a different top-level domain, first deactivate it from the current domain.

## Deactivate a domain

You can deactivate a license key from its current domain in the Online CMS Editor:

1. Open the Online CMS Editor.
2. Go to **Workspace > License**.
3. Select **Deactivate this domain**.

This automatically deactivates the current top-level domain and makes the license key available to use on another domain instantly.

## Still cannot find it?

If you cannot find the receipt, access the Creem customer portal, or view the license key from your Online CMS Editor installation, [contact Realmac support](https://www.realmacsoftware.com/support/) and we can help retrieve it for you.
