Replace your license key
Enter the email you bought Lumi with, and we'll send a link that replaces your key. A lost key can't be resent, only replaced.
Your old key has stopped working, and the Mac using it will ask for the new one. Open in Lumi fills in the key, and Lumi asks before activating it. Or paste the key in Lumi's Settings → License.
This page replaces your key. You can also manage the subscription itself at link.com.
