About ClaimsIdentity

Say

List<Claim> claims = new List<Claim>();
            claims.Add(new Claim(ClaimTypes.Name, "Me", ClaimValueTypes.String, "http://contoso.com"));
            claims.Add(new Claim(ClaimTypes.Role, "Administrator", ClaimValueTypes.String, "http://contoso.com"));
            claims.Add(new Claim("EmployeeNumber", "123456", ClaimValueTypes.String, "http://contoso.com"));
            claims.Add(new Claim(ClaimTypes.DateOfBirth, "1900-01-01", ClaimValueTypes.Date, "http://contoso.com"));
            claims.Add(new Claim("AccessToken", DateTime.Now.AddMinutes(1).ToString(), ClaimValueTypes.String, "http://contoso.com"));
            var userIdentity = new ClaimsIdentity("Admin");
            userIdentity.AddClaims(claims);
            var userPrincipal = new ClaimsPrincipal(userIdentity);

Then you see url 

http://contoso.com

Does it matter if I change it to different one? Also I use "Admin" in 

var userIdentity = new ClaimsIdentity("Admin");

Is it okay if using a different one?
