I have created sign in policy in my azure active directory B2C tenant and trying to retain user credentials. On my login screen there is one checkbox "Keep me sign in" which is not working. Even if I check keep me sign in checkbox, I am not able to retain user password on IE, Firefox browser. However this is working for Chrome only because it retain user credentials by default.
Please suggest me how can we overcome this problem. Can we retain user credentials on AADB2C sign in page?
I have created new signin policy in azure ad b2c and use this policy for sign in page. Sign in policy has "keep me signed in" functionality by default. We dont need to write any code. Browser will take care of session management. Whenever we mark"keep me signed in" checkbox check, browser stores user credentials on browser and we do not need to re-enter password again. It will redirect to our page.
Thank You,

The disturbing scenario is: users log out of the application but their session remains valid such that they are able to sign back in without reauthenticating. Is the below code snippet the portion of the code that needs to be configured for the B2C session behaviour?
app.UseRewriter(
new RewriteOptions().Add(
context =>
{
if (context.HttpContext.Request.Path == "/MicrosoftIdentity/Account/SignedOut")
{ context.HttpContext.Response.Redirect("/Home/Index"); }
}));
When you want to sign the user out of the application, it isn't enough
to clear the application's cookies or otherwise end the session with
the user. Redirect the user to Azure AD B2C to sign out. If you fail
to do so, the user might be able to reauthenticate to your application
without entering their credentials again
The logout endpoint can receive an optional post_logout_redirect_uri parameter in the query string, where you can specify another URL where your user will be finally redirected by B2C. That can be the address of any resource, e.g. you homepage or your own page showing a "You successfully logged out of our service" message to the user.
post_logout_redirect_uri - The URL that the user should be redirected to after successful sign out. If it isn't included, Azure AD B2C shows the user a generic message.

I am using MS Graph in a desktop application so I am hosting a web browser in a form for the user to do their initial login. This all works fine and I can fully use MS Graph.
The problem I have is if we need to use an account of a different user there does not seem to be a way to reset the login. If you try to login again with the hosted web browser it will go right through and allow the same user.
The only way to reset it for another user seems to be to go into IE and delete the history/cache. Then the login screen will ask a user to login again. It seems a bit extreme to reset the cache.
So is this the only way to do this or is there something I can change in the MS Graph API call to tell it to reset?
You can force re-authentication by added prompt=login to the sign-in request:
Prompt (optional)
Indicates the type of user interaction that is required. The only valid values at this time are login, none, select_account, and consent.
prompt=login will force the user to enter their credentials on that request, negating single-sign on.
prompt=none is the opposite - it will ensure that the user isn't presented with any interactive prompt whatsoever. If the request can't be completed silently via single-sign on, the Microsoft identity platform endpoint will return an error.
prompt=select_account sends the user to an account picker where all of the accounts remembered in the session will appear.
prompt=consent will trigger the OAuth consent dialog after the user signs in, asking the user to grant permissions to the app.
I've been learning Auth0 for a React / React Native project. With two different apps now, including one from their site, I see the following behavior:
clear browser cache
login
enter password, now logged in
select logout
--> now logged out
select login
am NOT prompted for password again, just logged in without interaction.
It seems the session has been kept alive even though I logged out. I would expect that if I manually log out of an application, I must re-authorize with my password on the next login attempt.
As I said I've seen this twice now, once with my own project and once with the tutorial they provide at https://auth0.com/blog/react-tutorial-building-and-securing-your-first-app/ . Doesn't make any sense to me. Am I missing something?
Thanks ~~
This is the Seamless SSO behaviour explained here. This is now enabled by default on all tenants and it "seamlessly" logs the user in without showing any prompts if a session exists for the user in the Authorization server (Auth0 in this case). Previously you would get a prompt that said "Last time you logged in with ..." Clicking it would login you in without requiring a password.
If you are "Logging out" and yet you can log back in again without needing to enter credentials, the most likely explanation is that you are actually not calling the https://YOUR_AUTH0_DOMAIN/v2/logout endpoint which logs out the user by clearing their SSO cookie in Auth0. You can confirm this endpoint is called from Network tab in your browser when you click to logout.
The Auth0 React quickstart by default does not call the logout endpoint, it only removes the tokens from browser storage. To clear the SSO cookie and logout from IdP using Auth0.js you need to call the logout function as well. Refer to the Auth0.js logout function here.
Hope that helps.
We have a B2C custom policy for authentication but I am having trouble getting a consistent complete logout. The only way I have been able to get a complete logout of single sign on is to use the common endpoint:
https://login.microsoftonline.com/common/oauth2/logout?post_logout_redirect_uri={our homepage}
Then when I login I see this
Then I click sign in and see this
but even this does not always work. Sometimes it does not redirect but just sits on the "you have been logged out" screen.
Using the logout endpoint given in our metadata endpoint does not work as expected. I see the sign in screen (first image) but I cannot choose which account to login with I just click the button to sign in. I assume this means single sign on logout has not worked.
https://login.microsoftonline.com/te/{tennant}/{b2c-policy}/oauth2/v2.0/logout?post_logout_redirect_uri={our homepage}
How can I either get the first one to work every time or the second one to logout completely?
EDIT: Sorry I should have mentioned I am using node.js/javascript but any url type solution will work also. Also we are using B2C so the application is registered on that tenant. There is no option for a lotout url on this page.
In order to logout the user from B2C, you need to redirect your user to the B2C logout endpoint, not to the common endpoint. This should look like:
https://fabrikamb2c.b2clogin.com/fabrikamb2c.onmicrosoft.com/oauth2/v2.0/logout?p=b2c_1_sign_in&post_logout_redirect_uri={your homepage}
Be sure you redirect the browser to that endpoint and don't try to do a GET through a back-channel, otherwise it will not do anything as the Single Sign-in mechanism is based on browser cookies.

If I understand you correctly, you are trying to configure single sign out? This can be done but requires configuration separate from the sign-on configuration.
In the Accounts Controller you need to add a SingleSignOut action.
public ActionResult SingleSignOut(string redirectUri)
{
if (redirectUri == null)
ViewBag.RedirectUri = "https://localhost:44308/";
else
ViewBag.RedirectUri = redirectUri;
HttpContext.GetOwinContext().Authentication.SignOut(CookieAuthenticationDefaults.AuthenticationType);
return View();
}
See this tutorial and the accompanying repository.

We're working on a SAAS application that has recently been configured to use Azure ADAL for authentication. If it matters, we're going the oauth2 route, with response_type: code.
However, when we're testing the application, if the browser has been signed into an Azure account that does not belong to the tenant acting as identity provider, the prompt for password is bypassed, and the login fails on the Azure screen, saying AADSTS50020 - user not found in tenant.
On the one hand, congratulations to Azure for finding an already signed in user! On the other hand, there is no recourse to elect to not use this signed in user; it does not give the user the chance to interject with credentials that work.
How can we prevent this?
The core issue is we don't want users, visiting our site and ready to sign in, to have to have already signed out of Azure before trying to log in with our site.
Thanks in advance.

You could find when requesting an authorization code during code flow , there is a Parameter :prompt indicates the type of user interaction that is required .
Valid values are:
login: The user should be prompted to reauthenticate.
select_account: The user is prompted to select an account, interrupting single sign on. The user may select an existing signed-in account, enter their credentials for a remembered account, or choose to use a different account altogether.
consent: User consent has been granted, but needs to be updated. The user should be prompted to consent.
admin_consent: An administrator should be prompted to consent on behalf of all users in their organization
You could use prompt=login forces the user to enter their credentials on that request, negating single-sign on
