how to get claims of another user using ASP.NET Core

I'm still learning identities with core. I'm doing a claims-based token authorization.
Most examples are about "Current" logged in user. In my case my RPC service is receiving a username & password of some user in the identity DB. I need to

  1. verify that a user with such credentials exist

  2. get all the claims of that user

so to verify if the user exists, I'm using this:

ApplicationUser applicationUser = await _userManager.FindByNameAsync(username);
bool exist = await _userManager.CheckPasswordAsync(applicationUser, password);
if (!exist)
// log and return

I don't know how to do the 2nd step properly. I guess I could do a simple linq to collect all user's claims, but I'm sure there is a better way using the identity methods.

You need to use the GetClaimsAsync() method. For example:

var claims = await _userManager.GetClaimsAsync(applicationUser);
