ClaimsProvider extracts options/preferences from user claims. It has save and auto-create capabilities.

Its Prefix must be passed in the constructor, and it is Enabled only when the user is logged in.

Below the list of all provider specific properties:

        public string SourcePrefix { get; set; }
        public bool PersistentSignIn { get; set; }
        public string AuthenticationMethod { get; set; }
        

With:

SourcePrefix

Prefix all claims must have, to be processed by the provider. This prefix is removed before each field name is concatenated with Prefix to get the final path in the request dictionary. Since claim names usually have an URI format like: "http://www.mvc-controls.com/Welcome", for instance, once extracted from claims paths have their / replaced by dots. The inverse operation is performed before saving back settings into claims.

PersistentSignIn

Declares if persistent sign in must be used when re-logging after an user claims modification

AuthenticationMethod

Declares the authentication method name to use when re-logging after an user claims modification

Both PersistentSignIn and AuthenticationMethod are the standard parameters usually passed to the SignInAsync method of the SignInManager. See here for an introduction to authentication and SignInManager.
