Frequently Asked Questions


When does my subscription start?

Your Bitdefender subscription starts as soon as you make the purchase. The countdown begins immediately after you buy the code from our online store at, even if you haven’t redeemed it in your Bitdefender Central account yet. So, the subscription starts on the day you place the order, not on the day you activate the code in Bitdefender Central.


How can I tell if my new subscription was correctly activated?

You can check your subscription status and the expiration date of any subscription activated so far in your Bitdefender Central account. Open the My Subscriptions panel to find out if your new Bitdefender subscription was successfully activated.


Do I need the activation code each time I install Bitdefender?

No. Bitdefender codes only need to be activated once and may only be activated in one Bitdefender Central account. Once the subscription is active, the activation code is no longer needed in the (re)installation process, as all installations are managed directly from your Bitdefender Central account.


I renewed my Bitdefender subscription, but the product expired

If you purchased a subscription and the new validity is not reflected in the installed product, just log out and log back in again to your Central account using the Switch Account button (see the image below for reference). That should refresh your Bitdefender account and allow you to use the renewed subscription.

How do I install Bitdefender on my devices?

You don’t need to reinstall Bitdefender on devices that are already protected.

If you’ve already activated the subscription and need help with the installation process on a new device, first log in to your Bitdefender Central account. Select the My Devices panel, then click + Install Bitdefender products on your devices and follow the on-screen steps to install Bitdefender.

If you are already logged in, simply click this link to automatically land on the Install Bitdefender products section.
