# Are logged-in Shopify customers identified automatically or do I call identify myself?

Asked by darren_f on 2026-07-07. Tags: shopify, hydrogen, identity.

Wiring Croct into a Hydrogen store that uses Shopify customer accounts. Simple
question first: if a customer is logged in, does their identity flow through to
Croct automatically, or do I need to call identify somewhere in the login flow?

Then the edge cases. What happens on logout, does the profile stay attached to
the browser? Guest checkout, is that just an anonymous session? And the awkward
one, a shared family iPad where two different accounts log in and out of the same
browser. Want to make sure we dont end up personalizing for the wrong person.

No manual call needed for the happy path. With Shopify customer accounts,
logged-in customers are identified on every request, the Hydrogen SDK picks the
identity up from the session automatically. Identity resolution then links the
anonymous journey to the identified profile, so nothing the visitor did before
logging in is lost.

Your edge cases:

- Logout: the automatic path follows the Shopify session, so once the customer
  session ends the requests stop carrying that identity. If you have an explicit
  logout flow and want to be strict about it, `croct.anonymize()` exists exactly
  for that, it detaches the user and starts a fresh anonymous context.
- Guest checkout: yes, that stays an anonymous session unless the visitor logs
  in. The events still flow, they are just attached to the anonymous profile.
- Shared iPad: this is the main reason to call `croct.anonymize()` on logout.
  Each login is identified per request, so account B gets identified as account
  B once they sign in, but anonymizing on logout keeps the in-between anonymous
  browsing from being ambiguous.

Perfect, added anonymize to the logout action and left the rest automatic.
