  Hi,

  Step 1 Disable Self registeration

  

  Step 2

  Create a role

  if you don't want to manually create a role you can use dataseeder to seed the role data make sure to mark the role as default so newly created user will have that role automatically https://docs.abp.io/en/abp/latest/Data-Seeding

  step 3 : create a Register.cshtml in AuthServer Project

  Step 4: Inside register.cshtm place this code

  using Microsoft.AspNetCore.Mvc;
  using Microsoft.Extensions.Logging;
  using System.Linq;
  using System.Security.Claims;
  using System.Threading.Tasks;
  using Volo.Abp;
  using Volo.Abp.Account;
  using Volo.Abp.Account.Public.Web.Pages.Account;
  using Volo.Abp.Account.Settings;
  using Volo.Abp.DependencyInjection;
  using Volo.Abp.Identity;
  using Volo.Abp.Identity.Settings;
  using Volo.Abp.Settings;
  
  namespace Acme.BookStore.Pages.Account
  {
      [ExposeServices(typeof(RegisterModel))]
      [Dependency(ReplaceServices = true)]
      public class AppRegisterModel : RegisterModel
      {
          public override async Task<IActionResult> OnGetAsync()
          {
              if (IsExternalLogin)
              {
                  await TrySetEmailAsync();
                  return await OnPostExternalInternalAsync();
              }else
              {
                  return await base.OnGetAsync();
              }
          }
  
          private async Task TrySetEmailAsync()
          {
              if (IsExternalLogin)
              {
                  var externalLoginInfo = await SignInManager.GetExternalLoginInfoAsync();
                  if (externalLoginInfo == null)
                  {
                      return;
                  }
  
                  if (!externalLoginInfo.Principal.Identities.Any())
                  {
                      return;
                  }
  
                  var identity = externalLoginInfo.Principal.Identities.First();
                  var emailClaim = identity.FindFirst(ClaimTypes.Email);
  
                  if (emailClaim == null)
                  {
                      return;
                  }
  
                  Input = new PostInput { EmailAddress = emailClaim.Value };
              }
          }
  
  
          public virtual async Task<IActionResult> OnPostExternalInternalAsync()
          {
              try
              {
                  await SetUseCaptchaAsync();
  
                  IdentityUser user;
                  if (IsExternalLogin)
                  {
                      var externalLoginInfo = await SignInManager.GetExternalLoginInfoAsync();
                      if (externalLoginInfo == null)
                      {
                          Logger.LogWarning("External login info is not available");
                          return RedirectToPage("./Login");
                      }
  
                      user = await RegisterExternalUserAsync(externalLoginInfo, Input.EmailAddress);
                  }
                  else
                  {
                      var localLoginResult = await CheckLocalLoginAsync();
                      if (localLoginResult != null)
                      {
                          LocalLoginDisabled = true;
                          return localLoginResult;
                      }
  
                      user = await RegisterLocalUserAsync();
                  }
  
                  if (await SettingProvider.IsTrueAsync(IdentitySettingNames.SignIn.RequireConfirmedEmail) && !user.EmailConfirmed ||
                      await SettingProvider.IsTrueAsync(IdentitySettingNames.SignIn.RequireConfirmedPhoneNumber) && !user.PhoneNumberConfirmed)
                  {
                      await StoreConfirmUser(user);
  
                      return RedirectToPage("./ConfirmUser", new
                      {
                          returnUrl = ReturnUrl,
                          returnUrlHash = ReturnUrlHash
                      });
                  }
  
                  await SignInManager.SignInAsync(user, isPersistent: true);
  
                  return Redirect(ReturnUrl ?? "/"); //TODO: How to ensure safety? IdentityServer requires it however it should be checked somehow!
              }
              catch (BusinessException e)
              {
                  Alerts.Danger(GetLocalizeExceptionMessage(e));
                  return Page();
              }
          }
      }
  }
  
  
  

  Now whenever there will be external login registeration will skip the CheckSelfRegistrationAsync check

  Hi Anjali,

  thanks for the quick response. Using a default role helps, newly created users will see something. This resolves the 'remove cookies' step.

  However, I'm still figuring out how to bypass the enable self registration step. We use the ABP commercial package which seem to handle all user management and registration. I could not find the pages/account folder to put the register.cshtm file in. Is there a way to modify this behaviour?

  Another question with regards to the ABP commercial package: does it contain functionality to connect a google login after account creation?

  Thank you!

  Hi

  You have to manually create The folder and also create register.cshtml in Identity Server Web application

  and past the code which i have sent you in previous reply

  does it contain functionality to connect a google login after account creation? can you explain it with the scenario i am not able understand.

  you have to only register once after registration the login provider details get stored in these two tables along with the user created

  select * from [dbo].[AbpUserLogins]
  select * from [dbo].[AbpUserTokens]
  

  please explain with a scenario then will be able to provide you with more details

  Hi Anjali,

  does it contain functionality to connect a google login after account creation? can you explain it with the scenario i am not able understand.

  for example when we create user accounts, it would be convenient to have the following steps:

  1. as admin you create a user and set it's roles and organizational units
  2. as user you get an email, activate your account and login
  3. as user you want to use 2FA via google, and want to connect that to your account. So you can use that for future logins.

  Step 3 is, as far as I know, not possible at the moment? Note: we use the commercial packages.

  Hi

  2FA is provided by abp commercial you just need tp enable it from the account settings https://docs.abp.io/en/commercial/latest/modules/identity/two-factor-authentication

  if you want to enable 2FA with Google Authenticator please see here https://docs.microsoft.com/en-us/aspnet/core/security/authentication/mfa?view=aspnetcore-6.0
