Afternic had been acquired by GoDaddy back in 2013 and has largely remained operating as its’ own separate entity since then.
More recently however, it has introduced a for-sale landing page with GoDaddy branding, and the ability for customers to list domains for sale on the platform from within their GoDaddy account.
A response from customer service when asked about the specifics of the new login feature:
“If you link your Afternic account to your Godaddy login you will be able to login to your Afternic account using your Godaddy credentials. Any Premium Listings you have created through your Godaddy account will be merged with your Aftenic listings and will be opted in to the Fast Transfer process.”
Fast Transfer is a feature in which a qualifying domain name will be transferred directly to the buyer’s account after purchase at a participating Premium Network registrar.
