What is the purpose for adding ConCurrentUserId property and how it will be useful

It stores the currently loggedin concurrent ID and adds it to user claims.

Check the concurrent ID in the middleware, logout if it is different.

Thank you, this is working but it is not redirecting to login page for previous browser

{
   IConfigurationRoot _config = new ConfigurationBuilder().SetBasePath(Directory.GetParent(AppContext.BaseDirectory).FullName)
  .AddJsonFile("appsettings.json", false).Build();
  string webBaseUri = _config.GetSection("WebUISetting:URL").Get<string>();
  if (remoteError != null)
  {
      Logger.LogWarning($"External login callback error: {remoteError}");
      return RedirectToPage("./Login");
  }

  await IdentityOptions.SetAsync();

  var loginInfo = await SignInManager.GetExternalLoginInfoAsync();
  if (loginInfo == null)
  {
      Logger.LogWarning("External login info is not available");
      return RedirectToPage("./Login");
  } 

  var userName = loginInfo.Principal.FindFirstValue(ClaimTypes.Name);

  var result = await SignInManager.ExternalLoginSignInAsync(
      loginInfo.LoginProvider,
      userName,
      isPersistent: false,
      bypassTwoFactor: true
  );

  if (!result.Succeeded)
  {
      **await IdentitySecurityLogManager.SaveAsync(new IdentitySecurityLogContext()
      {
          Identity = IdentitySecurityLogIdentityConsts.IdentityExternal,
          Action = "Login" + result
      });**
  }

  var user = await UserManager.FindByNameAsync(userName);
  if (result.Succeeded && user != null)
  {
      var activeUserOrganizationUnitMappings = await _userOrganizationUnitExt_TRRepository.GetListAsync(x => x.UserId == user.Id && x.IsActive);
      if (user.IsActive && activeUserOrganizationUnitMappings != null && activeUserOrganizationUnitMappings.Any())
      {
          user.SetProperty(CommonConsts.ConCurrentUserId, new Guid().ToString("N"));
          await UserManager.UpdateAsync(user);
          await SignInManager.SignInAsync(user, false);

         await IdentitySecurityLogManager.SaveAsync(new IdentitySecurityLogContext()
          {
              Identity = IdentitySecurityLogIdentityConsts.IdentityExternal,
              Action = result.ToIdentitySecurityLogAction(),
              UserName = user.Name
          });

          return RedirectSafely(returnUrl, returnUrlHash);
      }
      
  }
  
}

I tried this, but still, I'm able to do the login in two different browsers at the same time.

What is the purpose for adding ConCurrentUserId property and how it will be useful? Also, on every login we need to assign same value for same user or different value?

As per the sample code, I need to add like this

user.SetProperty(ConcurrentLoginConsts.ConcurrentLoginToken, Guid.NewGuid().ToString("N")); await UserManager.UpdateAsync(user); return await base.PasswordSignInAsync(user, password, isPersistent, lockoutOnFailure);

In sample code we are using PasswordSignInAsync, will it work with SignInAsync as well? or SignInWithClaimsAsync is required after adding this ?

If I just add this code, will it be enough?

              user.SetProperty("ConCurrentUserId", Guid.NewGuid().ToString("N"));
                await UserManager.UpdateAsync(user);
                await SignInManager.SignInAsync(user, false);

Could you please help with an example, how can I change the current Principal to override the ICurrentUser ?
