在 Azure AD B2C 注册用户并使用用户名登录

Question

I made an application that creates a user in Azure AD B2C throught Microsoft Graph API

    var user = new User()
    {
          CreatedDateTime = DateTime.UtcNow,

          MailNickname = command.DocumentNumber,
          UserPrincipalName = $"{command.DocumentNumber}@*********.onmicrosoft.com",

          DisplayName = command.DisplayName,
          GivenName = command.GivenName,
          Surname = command.Surname,
          Mail = command.Mail,
          MobilePhone = command.MobilePhone,
    
          AccountEnabled = true,
          PasswordProfile = new PasswordProfile()
          {
              Password = "ABCabc123!*.",
              ForceChangePasswordNextSignIn = true
          },

          CreationType = "LocalAccount",
          PreferredLanguage = "es-ES",

          Identities = new List<ObjectIdentity>
          {
             new ObjectIdentity()
             {
                SignInType = "userName",
                Issuer = "******.onmicrosoft.com",
                IssuerAssignedId = command.DocumentNumber
            }
        }
    };


    var graphClient = _graphService.GetGraphServiceClient();

    var userCreated = await graphClient.Users.Request().AddAsync(user);

After that, we can see the user inside Azure AD B2C

Then, I want to reset password with specific User Flow created in B2C but it returns an error: An account could not be found for the provided user ID.

Any suggestion?

From your first screenshot, I can see that you added a user with name Sergio[...] and user name 53[...] . Then I guess that you try to reset the password with 53[...] as Id but 53[...] is the user name.

When creating a user , a guid is generated which is then used as Id . You have to use this Id or the userPrincipalName because these values are unique and enable to identify the specific user.

Here is an example response you get after creating a new user:

HTTP/1.1 201 Created
Content-type: application/json

{
    "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#users/$entity",
    "id": "87d349ed-44d7-43e1-9a83-5f2406dee5bd",
    "businessPhones": [],
    "displayName": "Adele Vance",
    "givenName": "Adele",
    "jobTitle": "Product Marketing Manager",
    "mail": "AdeleV@contoso.onmicrosoft.com",
    "mobilePhone": "+1 425 555 0109",
    "officeLocation": "18/2111",
    "preferredLanguage": "en-US",
    "surname": "Vance",
    "userPrincipalName": "AdeleV@contoso.onmicrosoft.com"
}
