We are trying to block the federated user from azure ad b2c custom policies.
following the sample from https://github.com/azure-ad-b2c/samples/tree/master/policies/disable-social-account-from-logon
Issue:
When running the custom policies with our saml assertion from samples, when the federated user is logged in from the external IDP below page is triggered
The page after signin of federated user with the output claim of federated user details.
B2C URL: https://tenant.b2clogin.com/tenant.onmicrosoft.com/B2C_1A_TrustFrameworkBase/samlp/sso/assertionconsumer
I need to skip this page and make silent signup of user to generated objectid ad b2c using AAD-CreateAlternativeSecurityId technical profile.
Issue 2:
Even with this page when I press continue, it throws an error "Unable to validate the information provided." not sure about this validation and how to overcome this error ?
In short, I need help on how to create a federated user in azure ad b2c automatically from the custom policies during signin and update extended user attributes for the federated user.
Remove the orchestration step which references the SelfAsserted-Social technical profile. This technical profile will ask the user to provide more information (displayName, givenName, surName) after sign up with a Social Account.
If these claims are mapped appropriately with the social account technical profile, then they will just get written to the directory in a later step by default.
To troubleshoot your policy, follow this.

I am implementing a passwordless signin experience for local B2C account users with MFA credentials through Azure B2C custom policies. I am using AzureMfaProtocolProvider with a custom attribute stored phone number as an sms MFA option, and OneTimePasswordProtocolProvider with a custom attribute stored email as an email MFA option. When I initiate a login, the first step us username retrieval. The username is used to read the mfa options from AD and then presented to the user as options. Once they select an option, a code is sent and they must successfully validate the code from one of the MFA options to issue a token to the application. This works great, however I noticed that Active Directory does not store and log a "sign in" in the signin logs (https://learn.microsoft.com/en-us/azure/active-directory/reports-monitoring/concept-all-sign-ins). Per the document, MFA challenges should generate a signin log but it seems that MFA challenges with these protocol providers (AzureMfaProtocolProvider/ OneTimePasswordProtocolProvider) are not sufficient.
I am concerned that we will miss inherent Active Directory risk tracking without "sign ins" being generated. I am also operating with a business requirement to see those logs generated for auditing purposes.
As a work around, I am adding a psuedo password to user accounts on creation and then faking a login with the "login-NonInteractive" technical profile, which validates the credentials in AD using OIDC. This successfully generates a signin log but it seems hacky. My question is what is the recommended approach to generate a signin log in Azure AD with a passwordless solution?

For this scenario, you can implement magic link in this web application user can click login button and then user is redirected to identity provider in azure ad b2c.
Now in custom policy page user can select the magic link option to authenticate and user has to provide the email address and continue azure ad b2c will send a request to magic link web application and then this web api responsible to generating the magic link which we sent to the user mailbox.
For more information in detail, please refer below links:

Azure B2C User Flow SignUp/SignIn with Email/Number.
Requirements:
SignUp with Email/Phone:
while signing up when user click for registration its shows already email/phone number exist but we are looking when user have already have email then it automatically move to login flow.
SignIn with Email/Phone:
while user click on the signin if user not exist then it automatically navigate to the signup page so user dont need to manuly go for signup
Forget Password with Email/Phone:
With the Email/Phone number signin/signup flow there is missing the reset password policy to change password and there is only showing the change phone number option.we need to reset the user password
There is missing the Cenel icon on the phone number signup flow.
I did reproduce your scenario and found that there is currently no prebuild option or system in user flow of Azure AD B2C that when user try to sign and if it has not already signup will redirect to signup page and vice versa.
Azure AD B2C offers various sign-up and sign-in options for users of your applications:
I did Configure my Azure AD B2C local accounts to allow sign-up and sign-in with using email address. There are also other ways with username, phone number, or a combination of methods.
For Forget Password with Email/Phone enable the self-server password under the properties of your created user flow.
Please follow this GIF for apply for Forget Password with email and attribute which I have set for my userflow.
I have shown the demo how my user flow is working please check this GIF as well.
I have redirected my webapp to https://vikashgaurav.com/portfolio/ after successful signing.

I'm trying to integrate Google identity provider to sign in user flow in Azure Ad B2C. while logging in with google id and password its redirecting to the page which I have provided but with an error "User does not exist. Please sign up before you can sign in."
It's working fine with Facebook Idp
If you are using SignIn only (and not SignUporSignIn flow), this behavior is expected if the user does not exist in the directory.
If you use a SignUporSignIn flow, user will be prompted to signup if they don't exist.
Can Azure AD B2C pass the "UserName/Email and Password" entered by end user to a third party trusted application for credentials validation and get the claims for the user on successful credentials validation by the App?
This scenario arises because, some of my users are in Azure AD B2C and some of the users are maintained in the custom user store and can't be moved to Azure AD B2C due to business reasons. Yet i want to provide same sign-in experience for both users.
The Wingtip sample contains an example of this integration.
See the "ClassicAccount" claims provider for reference.
This claims provider, which is implemented by a REST API, is integrated in to the sign-in user journey to sign users in using logins that are external to the Azure AD B2C directory.
Code for the REST API can be found in the same repository.
We have a Web App secured with Azure AD B2C using custom Identity Experience Framework policies to allow users to register and sign in with social identities (Microsoft, Google, Facebook), or with an identity from another federated Azure AD instance, or with 'local' Email / Password accounts.
All the social accounts and the Federated AD work correctly. Sign up and sign in with Email/Password was working correctly, but we are now experiencing an error. We haven't knowingly made any changes to our Email/Password configuration since this was last known to be working, so we're not sure how this has happened.
The issue is: Sign Up with a new Email Address works correctly, and after the process completes, the user is correctly logged-in, and their account appears in the directory. If the user signs out, however, then any attempt to sign back in again fails:
(Email address shown is not the actual one. Error has been repeated by multiple users with new and old email/password combinations.)
Digging into the portal, the underlying error is revealed as:
70001 The application named X was not found in the tenant named Y. This can happen if the application has not been installed by the administrator of the tenant or consented to by any user in the tenant. You might have sent your authentication request to the wrong tenant.
This error appears sometimes to be related to a failure to grant permissions to an application in the portal. We have tried removing and reinstating all permissions, and re-granting permissions. This has not solved the issue.
Does anyone know what could be causing this issue, and in particular why sign up / sign in works correctly, but returning sign in does not?
UPDATE:
Just to confirm that we have the IEF and Proxy IEF apps configured in the AD directory:
And we have the login-NonInteractive technical profile configured in TrustFrameworkExtensions.xml:
Having wired up Application Insights (following these instructions https://learn.microsoft.com/en-us/azure/active-directory-b2c/active-directory-b2c-troubleshoot-custom), we're able to get to this more detailed error:
AADSTS70001: Application with identifier
'ProxyIdentityExperienceFrameworkAppID' was not found in the directory
weapageengine.onmicrosoft.com
The only place 'ProxyIdentityExperienceFrameworkAppID' appears in any of our custom policies is shown in the XML snipped above, but this seems correct as per the documentation here: https://github.com/Azure-Samples/active-directory-b2c-custom-policy-starterpack/blob/3b4898fec3bf0014b320beffa6eb52ad68eb6111/SocialAndLocalAccounts/TrustFrameworkExtensions.xml#L38 - unless we are meant to update those 'DefaultValue' attributes as well?
Resolution:
As per the answer below, it is necessary to update both the Metadata and the default values with the relevant app ids. Worth noting that in the GitHub sample https://github.com/Azure-Samples/active-directory-b2c-custom-policy-starterpack/blob/3b4898fec3bf0014b320beffa6eb52ad68eb6111/SocialAndLocalAccounts/TrustFrameworkExtensions.xml#L38 the boilerplate values are differently cased, leading to our missing one in a replace-all:
The local account sign-in authenticates the end user against the Azure AD B2C directory and then reads the user object from it.
The local account sign-up and the social account sign-in do not authenticate the end user against the Azure AD B2C directory. The local account sign-up writes the user object to it. The social account sign-in delegates authentication to the social identity provider and then either writes the user object to the Azure AD B2C directory if the user object does not exist or reads the user object from the Azure AD B2C directory if the user object does exist.
To enable authentication of the end user by the local account sign-in against the Azure AD B2C directory, you must add the Identity Experience Framework applications to the Azure AD B2C directory and then configure these IEF applications with the login-NonInteractive technical profile.
The local account sign-up and the social account sign-in do not require these applications.
