There are two ways to activate your CyberGhost VPN serial number, or license key: either via our website, or via the CyberGhost VPN Windows client.

First, save the serial number emailed to you by one of our e-commerce partners. Then go to cyberghostvpn.com in order to activate your subscription through our website. Click on My Account. Enter your username and password to login.

On the right hand side menu, click on "Activate Serial Number." Enter the serial number you had saved earlier, and click on "Activate subscription." Wait a few moments and there you go. Your serial number has been activated.

Alternatively, you can activate your serial number through the CyberGhost VPN Windows client. After saving the serial number that you received via email, open the CyberGhost VPN client and enter your username and password to login. Once logged into your account, click on the "Activate license key" button. Enter your serial number, click OK and wait a few moments. You can now start enjoying your new CyberGhost VPN subscription.

Please note that if you already have a serial number activated on your account, be it a promo serial number or an older subscription, you won't be able to activate a new serial number. You may only do this when your current subscription expires.

If you would like to delete an ongoing subscription in order to activate a new one, please go to the "My Account" section on the website. In the right-side menu, choose "My Subscriptions". There you will see your subscription info, and you will be able to delete your current subscription. However, please think twice before deleting a subscription.
