You can manually add an activation code to your account to synchronize subscription information across your connected devices.
To activate your app through My Kaspersky:
If the code is added successfully, a corresponding panel appears in the Subscriptions section. Your apps that are compatible with the subscription and connected to your account will be activated. Additionally, a check is performed if the registered subscription should be sent to your connected devices manually. If so, you can select devices and send the subscription right away.
An activation code must be valid (the subscription should not be expired) and must not be banned, blocked or already added. You can add no more than 100 activation codes to your My Kaspersky account.
