# How to activate AdBlock on multiple computers

Your AdBlock license isn't tied to a single computer. You can use the same license key on several devices, up to the limit included in your plan. Activating AdBlock on another computer works exactly the same way as activating it on your first one: install the app, then enter your license key.

## How many devices can I use?

The number of computers you can activate depends on your plan:

| Plan   | Devices         |
| ------ | --------------- |
| Basic  | 1 device        |
| Pro    | 2 devices       |
| Family | Up to 5 devices |

You use the **same license key** on every device. There's no separate key for each computer.

> **Before you start:** have your license key ready. It's in the activation email you received when you purchased AdBlock, and it's the same key you used on your first computer.

## Activate AdBlock on another computer

1. **Install AdBlock** on the new computer if you haven't already. See [How to install AdBlock](/docs/getting-started/how-to-install-adblock.md).
2. Open the **AdBlock** app and click **Subscription** in the left-hand menu.
3. On the Subscription page, click the **Add License** button.
4. In the **Add License** window that opens, paste your license key into the **License Key** field, then click **Activate**.
5. That's it. You'll see a **"Your license has been activated"** confirmation in the bottom-right corner, and your license status will change to **Valid**. AdBlock is now protecting this computer too.

> **Tip:** These are the same steps covered in [How to activate your AdBlock license](/docs/guides/how-to-activate-adblock-license.md).

## Reached your device limit?

If you've already activated AdBlock on the maximum number of devices for your plan, you have two options:

* **Free up a slot.** On the **Subscription** page, under **Device Management**, you can see the computers currently using your license and remove one you no longer use. This frees a slot for a new device.
* **Need more devices?** If your plan doesn't cover enough devices, open **Help & Support** in the AdBlock app (bottom-left corner) to get in touch with our team, and we'll help you upgrade your license.
