machine identification using web api

Question

I want to implement device detection mechanism. How can we detect if the user is using the same machine for login to our application that he had used earlier? If user is using his machine that he had used for first time then skip security question else for new machine show him security question.

 

I am using .Net core 2.1 web API with no database and angular 6 to develop front-end.

 

Please provide your suggestions. Many thanks in advance.
