Hi @Allan Fernandes ,
If you signed up for your subscription after August 2018 and you're an active developer, your subscription will be renewed automatically for another 90 days from the original date of expiration.
If you signed up for your subscription before then, your subscription is not renewable and you'll need to set up a new one when it expires.
In addition, It's not supported to sign in to the Developer Program dashboard with existing domain account.
