# Obtaining a license key

Follow this guide to get the license key necessary to activate your purchased premium features or to white-label CKEditor 5 (remove the “Powered by CKEditor” logo).

# Log in to the CKEditor Ecosystem dashboard

Log in to the CKEditor Ecosystem dashboard. If this is the first time you do it, you will receive a confirmation email and will be asked to create a password for your account. Keep it safe.

# Access the account dashboard

After logging in, click “CKEditor” under the “Your products” header on the left. You will see the overview of the subscription parameters together with the management area below.

# Copy the license key

After clicking “Manage,” you can access the license key needed to run the editor and the premium features. Note that the same license key will be valid for both the Productivity Pack and other standalone features, as well as CKEditor 5 itself.

There are two license keys available:

1. The old key for versions older than 38.0.0.
2. The new key for versions 38.0.0 and later.

The new key available is the new format license key that is only valid for versions 38.0.0 or later. The old key will work with all CKEditor 5 versions up to the version to be released in May 2024 (when we consider removing support for these keys) as long as the key is not expired.

# Activating the product

You need to add the license key to your CKEditor 5 configuration. It is enough to add the license key once for the standalone features listed in this guide, no matter which and how many premium features you intend to use.

ClassicEditor
    .create( document.querySelector( '#editor' ), {
        // Load the plugin.
        plugins: [ /* ... */ ],

        // Provide the activation key.
        licenseKey: 'your-license-key',

        // Display the feature UI element in the toolbar.
        toolbar: [ /* ... */ ],
    } )
    .then( /* ... */ )
    .catch( /* ... */ );

To use premium features, you need to add the relevant plugins to your custom CKEditor 5 build. You can use the online builder to generate a CKEditor 5 build with the plugin enabled.

Alternatively, refer to the installation sections in the plugin documentation to do it on your own. You can read more about installing plugins and toolbar configuration in dedicated guides.
