  Hello

  https://community.abp.io/posts/how-to-add-a-custom-grant-type-in-openiddict.-6v0df94z

  I am trying the above solution but it is not working because I am using a separate auth server (openIddict). Please provide any proper solution for Passwordless authentication. My requirement is to first generate a passwordless login url and send it to the user in mail inbox and the user clicks on the passwordless login url then redirects to angular application with authentication.

  thanks

  Hi,

  This article also applies to Angular UI https://community.abp.io/posts/implementing-passwordless-authentication-with-asp.net-core-identity-c25l8koj

  You just need to redirect to the angular website in the publicclassPasswordlessController.

  For example:

  using System;
  using System.Threading.Tasks;
  using Microsoft.AspNetCore.Mvc;
  using Volo.Abp.AspNetCore.Mvc;
  using Volo.Abp.Identity;
  using Volo.Abp.Identity.AspNetCore;
  
  namespace PasswordlessAuthentication.Web.Controllers
  {
      public class PasswordlessController : AbpController
      {
          protected IdentityUserManager UserManager { get; }
  
          protected AbpSignInManager SignInManager { get; }
  
          public PasswordlessController(IdentityUserManager userManager, AbpSignInManager signInManager)
          {
              UserManager = userManager;
              SignInManager = signInManager;
          }
  
          public virtual async Task<IActionResult> Login(string token, string userId)
          {
              var user = await UserManager.FindByIdAsync(userId);
  
              var isValid = await UserManager.VerifyUserTokenAsync(user, "PasswordlessLoginProvider", "passwordless-auth", token);
              if (!isValid)
              {
                  throw new UnauthorizedAccessException("The token " + token + " is not valid for the user " + userId);
              }
  
              await UserManager.UpdateSecurityStampAsync(user);
  
              await SignInManager.SignInAsync(user, isPersistent: false);
  
              var ngAppUrl = "http://localhost:4200/account/login"
              return Redirect(ngAppUrl);
          }
      }
  }
