# License Key
|
|
|
|
To enable certain licensed features, you must first activate your license. You can do this either through the UI or by setting environment variables.
|
|
|
|
## Add a license key using the UI
|
|
|
|
In your n8n instance:
|
|
|
|
1. Log in as **Admin** or **Owner**.
|
|
1. Select **Settings** > **Usage and plan**.
|
|
1. Select **Enter activation key**.
|
|
1. Paste in your license key.
|
|
1. Select **Activate**.
|
|
|
|
## Add a license key using an environment variables
|
|
|
|
In your n8n configuration, set `N8N_LICENSE_ACTIVATION_KEY` to your license key. If the instance already has an activated license, this variable will have no effect.
|
|
|
|
Refer to [Environment variables](/hosting/configuration/configuration-methods.md) to learn more about configuring n8n.

|
## Allowlist the license server IP addresses
|
|
|
|
n8n uses Cloudflare to host the license server. As the specific IP addresses can change, you need to allowlist the [full range of Cloudflare IP addresses](https://www.cloudflare.com/ips/) to ensure n8n can always reach the license server.
