Straight answer is that you should get all information inside Claims. Now whoever handling Claims server is responsible to pass all information inside Claims. Below is the code section which can use to loop through each of the claims, where " System.Security.Claims.ClaimsIdentity" is the main class . I also put an HTML screen shot of the output, once you loop through Claims using below code. This is a wide area and so you should read and expand your knowledge based on what shared here. //Storing main details in ViewBag var userClaims = User.Identity as System.Security.Claims.ClaimsIdentity; //You get the user’s first and last name below: ViewBag.Name = userClaims?.FindFirst( "name" )?.Value; // The 'Name' claim can be used for showing the username ViewBag.Username = userClaims?.FindFirst(System.IdentityModel.Claims.ClaimTypes.Name)?.Value; // The subject/ NameIdentifier claim can be used to uniquely identify the user across the web ViewBag.Subject = userClaims?.FindFirst(System.Security.Claims.ClaimTypes.NameIdentifier)?.Value; // TenantId is the unique Tenant Id - which represents an organization in Azure AD ViewBag.TenantId = userClaims?.FindFirst( "http://schemas.microsoft.com/identity/claims/tenantid" )?.Value; //Read from ViewBag inside View Main Claims:h3> class = "table table-striped table-bordered table-hover" > Nametd> @ViewBag.Nametd>tr> Usernametd> @ViewBag.Usernametd>tr> Subjecttd> @ViewBag.Subjecttd>tr> TenantIdtd> @ViewBag.TenantIdtd>tr> table> //Loop through all Claims All Claims:h3> class = "table table-striped table-bordered table-hover table-condensed" > @ foreach (var claim in ((System.Security.Claims.ClaimsIdentity)User.Identity).Claims) { @claim.Typetd> @claim.Valuetd>tr> }
