Northern Trail Outfitters want to allow its consumer to self-register on it business-to-consumer (B2C) portal...

To enable self-registration using person accounts for consumers on a B2C portal built on Experience Cloud, the identity architect should configure three steps:

Enable access to person and business account record types under Public Access Settings. Public Access Settings are settings that control the access level and permissions for guest users onExperience Cloud sites. By enabling access to person and business account record types, the identity architect can allow guest users to create person accounts or business accounts when they self-register on the portal.

Under Login and Registration settings, ensure that the default account field is empty. Login and Registration settings are settings that control the login and registration options for Experience Cloud sites. By ensuring that the default account field is empty, the identity architect can prevent guest users from being associated with a default account when they self-register on the portal.

Contact Salesforce Support to enable person accounts. Person accounts are a type of account that combines an individual consumer with an account record. Person accounts are not enabled by default in Salesforce orgs and require contacting Salesforce Support to enable them.
