How to restrict customer login to one device at a time in Shopify?

Shopify Discussion

I need to implement a login restriction in a Shopify store where a customer can be logged in on only one device at a time.

If the same customer logs in from another device or browser, the previous session should be automatically logged out.

I understand that Shopify does not support this functionality natively.

I would like to know:

  1. Is there any verified third-party Shopify app that supports single-device login or session invalidation?
  2. If not, is it possible to achieve this using a custom app or the Customer Account API?

Any confirmed guidance or real-world implementation details would be appreciated.

Hi @charcodeit

There is currently no verified third-party app in the Shopify App Store that specifically offers “single concurrent device” restriction.

Most security apps focus on locking content or restricting access by tag rather than managing active session states.

However, you can achieve this by building a custom system that checks for a valid session token on every page load and forces a logout if the token is outdated. But of course, just like it sounds, this can be really complicated.

Hope this helps!
