<3 <3 OR Home Page - Buddy Auth Portal click register but remember to. Make sure you use the same email address you used while purchasing your Buddy product.

After that wait a few min log in and the key should automatically be added to your account as long as you use the same email address you used while purchasing your Buddy product
