In one Web Api Net Core solition I used Microsoft.AspNetCore.Identity.EntityFrameworkCore for Authentication. It’s really comfortable to work with this package because you a free from the implementation of all the methods and don’t spare much time. It also returns the text of errors, for example, that password is to short or special character is required. For me everything was ok, but the customer wanted to see the text in German.

There’s a nice online tool for rendering the test data. It’s at the website https://www.mockaroo.com/. I often use it to render fake SQL data. But now I am working on a Net application with EF Core. And obviously, I need test data for webservices and interfaces. Below is the way to quickly insert the test data in the Net solution.
