In my application, I'm doing external login (ADFS login), once it is success on ExternalLogincallback, I'm calling ExternalLoginSignInAsync as below
var result = await SignInManager.ExternalLoginSignInAsync( loginInfo.LoginProvider, userName, isPersistent: false, bypassTwoFactor: true );
once it is also successful, I'm calling below function
await SignInManager.SignInAsync(user, false);
but using these steps I'm not able to prevent concurrent login in two browsers, I have found the existing solution https://support.abp.io/QA/Questions/1023/How-to-prevent-ConCurrent-Users-from-logging-in-using-the-same-user-credentials
By following this I can add MyAbpClaimsPrincipalContributor and MyAbpClaimsService but I'm not sure, how I can implement in my application, could you please help me where can I use this in my application when I'm using ExternalLoginSignInAsync and SignInAsync.

Hi,
We have an example you can check: https://github.com/abpframework/abp-samples/tree/master/ConcurrentLogin

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); -

It looks fine.

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?

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.

Hi,
Could you explain it in detail? thanks
using this code, it is not redirecting to login page, I want if new session is active in new browser, then the previous browser's application should redirect to login page.
if (httpContext.User.Identity != null && httpContext.User.Identity.AuthenticationType == "Identity.Application") { await httpContext.RequestServices.GetRequiredService<AbpSignInManager>().SignOutAsync(); await httpContext.ChallengeAsync("Identity.Application"); } //JWT if (httpContext.User.Identity != null && httpContext.User.Identity.AuthenticationType == "AuthenticationTypes.Federation") { await httpContext.ChallengeAsync(JwtBearerDefaults.AuthenticationScheme); } -

Hi,
So, preventing concurrent logins from different browsers is working now but the previous browser did not redirect to the login page
You can redirect:
if (httpContext.User.Identity != null && httpContext.User.Identity.AuthenticationType == "Identity.Application") { await httpContext.RequestServices.GetRequiredService<AbpSignInManager>().SignOutAsync(); //await httpContext.ChallengeAsync("Identity.Application"); var redirectUrl = "..."; httpContext.Response.Redirect(redirectUrl); return; } -
