Disable soft login
A logged-out shopper can still see personalized content based on their profile.
This is referred to as soft login. Soft login allows a registered shopper who is returning to the site to be identified and their site experience to be personalized.
Soft login is a per site setting, and is enabled by default. You can use the /ccadmin/v1/merchant/profilePolicies
REST API endpoint to disable it. See Create a shopper profile for details.
A shopper who is soft logged-in must log in to access their account page or to create an order.
