Subject: Locked out of Developer Edition org — registered email domain no longer exists

Hi Salesforce Community,

I'm unable to access my old Salesforce Developer Edition org because Salesforce requires an email verification code, but the registered email address belongs to a domain that no longer exists.

I'm the only System Administrator in this org, and I don't have another authorized session or existing Salesforce CLI connection.

Is there an official process to recover access or update the registered email address after verifying ownership?

I'd appreciate any guidance on the available recovery options.

Thank you!
