Read access_token from logged in user

How can I from a controller get the tokens for the authorized user? I have tried something like this but the token list is seems to be empty.

var userResult = await HttpContext.AuthenticateAsync();
var user = userResult.Principal;
var tokens = userResult.Properties.GetTokens().Select(token => new string[] { token.Name, token.Value });

Is this the correct way to get hold of the tokens?
