Beginner setting up architecture

I'm new the MVC CORE 2.0 and I want to determine a good strategy for setting up all of the web.apis that I am going to develop. I want to develop small services that are all secured with token-based security using JWT.

I want to develop a web.api service that handles the security by accepting a username/password and returns a security token. I then want to use that token to pass into any other service that I want and use without re-authenticating.

First, does this approach seem reasonable?

Second, is this possible? If so, can you point me in a direction to learn how to do it?

Thanks.
