If a customer creates a verified account on my website, they will only be able to log in using the device they used during account creation. If they try to log in from a different device, that second device will be blocked.

Are there any online third-party tools that provide this kind of feature?

Not Shopify apps. I mean, some other service providers who can give this kind of service.
