Authentication system for a shopify theme

Job ID: 35788126

Budget: $250 – $750 USD

I need a protection system for a shopify theme that I'm going to release.
This system needs to work as follows:



The customer bought the theme in my store;
I generate an authentication key or login/password;
Customer put this authentication and can use theme only in your shopify store.
If someone tries to remove the code that does this authentication from the theme codes, the theme does not work and it is impossible to edit it in shopify or redirect to a page.
That is, the theme will be blocked, and it will only work with authentication, which only I have control over whether to release it or not.



Hope you can help me!

The most necessary requirement is that this authentication script should be as difficult to remove as possible... Or if it is removed, the theme will not work properly, it will be full of errors.

The problem that happens here is that I send this theme file, and then the client sends it in groups or to friends, sharing the theme with many people and making me lose money... I need an authentication method that the theme only works on URLs of the stores I allow.



If the store is not released by me, a message will appear like "contact the administrator to release your access to the theme" ... or ... "insert your license key"

I paid other freelancers to do this, but the authentication methods are very simple to remove.
