How to implement magic links for direct store access?

[triplesingle]

Does anyone know if such an app is possible or how to implement the following:

A Shopify store is locked behind a password until next week. However, I would like to grant early access to certain loyal customers by essentially giving them a link that allows them to bypass the password and entire directly into the store.

Once the link is used by a customer, it is "expired" and cannot be shared thus ensuring the early access of the store stays exclusive.
