First of all, sorry if this isn't the right place, and this might sound like a dumb request, but I totally forgot the mail I used to register onto HS and only have the hsPortalId, is there a way to retrieve the login mail just with that data, or its better to just created a new account? it was the development account anyway.
This isn't a stupid question! Unfortunately, for security reasons, it's not possible to recover a HubSpot account using the portal ID alone. If there isn't an administrator in the account that can help, you'll need access to the original email address you provided in order to access your account. This restriction exists to prevent malicious actors from accessing HubSpot accounts if they have access to the portal ID.
If you're unable to remember the original email address, and there aren't any other users in the account that can assist with recovery, it is probably best to create a new developer account.
