I would like to use the Azure B2C Identity Service for customer self registration, but I would like to add a manual verification. The user shall upload a scan of his ID card / passport. And shall not be granted (full) access before the manual verification by our back office.
Is such process possible out of the box, as I could only find a slide, but no more details or documentation. https://learn.microsoft.com/en-us/azure/active-directory-b2c/active-directory-b2c-overview#third-party-identity-verification-and-proofing
Thanks for any suggestions.
You need a customised user journey.
Each step would call REST API to do verfification etc.
There is no out-of-the-box solution.
You need to customize the user journey by referring to the custom policy.
Please refer to: Custom policies in Azure Active Directory B2C.

Can someone provide a general approach to meeting these requirements? I've spent a bit of time researching these various topics and attempting to implement solutions and I'm surprised at how much work is involved. Hopefully I'm missing something.
How do I invite consumer users to a B2C tenant so that they can authenticate into our application using their social accounts (ex: Personal Microsoft or Google accounts)? The only baked in solution on the Azure Portal I've found uses B2C local accounts. Note that I do not want to use a publicly accessible Sign Up flow.
Presently I'm looking into a custom process that would work by inviting users to a 'local' b2c consumer account and then allowing the user to associate their social account with the local account.
Once users have authenticated (using MSAL v2 Auth Flow w/PKCE), I want to retrieve a list of permissions the user has for our application.
I'm looking into two options here:
(1) use the auth token to verify user against an internal API that, in turn, makes a call to the Microsoft Graph API to get the user's group memberships.
(2) Create a custom claim that serves the same purpose as user groups
Administrative users of our application need to be able to invite additional users to the application.
I've found some articles that point, again, to using custom policies.
Thank you very much!
EDIT #1 -
Looking into using B2C & Microsoft Graph API I came across some decent, and recent, MS Resources:
https://learn.microsoft.com/en-us/azure/active-directory-b2c/microsoft-graph-operations
And this important-to-me statement -> Microsoft January 28th, 2021:
"Although the OAuth 2.0 client credentials grant flow is not currently directly supported by the Azure AD B2C authentication service, you can set up client credential flow using Azure AD and the Microsoft identity platform /token endpoint for an application in your Azure AD B2C tenant. An Azure AD B2C tenant shares some functionality with Azure AD enterprise tenants."
I'll update my post when I find a solution. Thanks again!
You need to use custom policies.
For first bullet point, see my sample:
https://github.com/azure-ad-b2c/samples/tree/master/policies/link-local-account-with-federated-account
You could do either option. For option 1, AAD B2C can call your api which can call graph api to fetch groups. Then embed the info into the token. For option 2, you could write a role value to an extension attribute and return it in the token.
To invite users, you could use the invite sample. Essentially make an app that calls an API to generate these invite links and send those to the users email. The user clicks the link which allows them to complete their sign up.
https://github.com/azure-ad-b2c/samples/tree/master/policies/invite
I have a project, implemented using react js and Azure B2C. For sign-in and password reset, I used azure built-in user policies. What I want is when I add a user with the 'create Zure Ad B2C user' option, I want the user to get an email (An invite). As I know B2C doesn't have this function yet. I found out that this might be solved by a custom policy. But I don't know how. Can anyone help me with this? Thanks in advance.
This type of process would not be handled by the B2C flows. A user creation task cannot be tied to an email being sent out from our service. You would rather follow something like this:
https://github.com/azure-ad-b2c/samples/tree/master/policies/invite
You would create the user via portal or Graph API. Then generate a link and send it via a mail provider to the users email containing the link to compete the registration, eg providing their password.
Agree with #Jas.
Have a look here to see something similar for the invite flow.
Note that you should use "id_token_hint" rather than the older "client_assertion".
I want to integrate Multi Factor Authentication (MFA) through Azure Active Directory (AD), I checked its documentation and some code samples, then I knew that Azure AD B2C have some of features which suits my requirement,
NOTE - I only need MFA feature from Azure AD B2C,
I tried this sample code provided in official docs, https://learn.microsoft.com/en-us/azure/active-directory-b2c/active-directory-b2c-tutorials-spa
But I have some of queries:
1) Is there any service in Azure B2C, which can directly provide MFA facility to integrate, without need to register users in Azure AD?
2) In Azure B2C, can I control user flow with information of my website? So that email and phone number will be of my website during user flow. (I am asking about this because according to my plan I am going to integrate it after login process in my website)
3) There are 3 types of account in Azure B2C, (Work account, Guest user, Consumer user), Which user type is most suitable? (I only need MFA for the user, and will require to manage users via Graph or any official API)
4) From where can I decide, which type of user will be registered? because the code which I have tried, doesn't mention about user type, (Actually I want to know that is there any param or option in user-flow, which can decide type of user, which will be registered through this flow)
Any help or suggestions will helpful for me,
Thanks in advance,
1. Is there any service in Azure B2C, which can directly provide MFA
facility to integrate, without need to register users in Azure AD?
Yes you can restrict new user to sign and sign up using MFA. For that need to enable MFA. Its global MFA for all.
See the screen shot below.
Note: You can also implement MFA for each individual user.
See the screen shot below for Individual MFA
Once you implement MFA you would be prompted to verify your phone
number like below
Note:
For Testing MFA Userflow need native application on application
drop down
See the screen shot below
2. In Azure B2C, can I control user flow with information of my
website? So that email and phone number will be of my website during
user flow. (I am asking about this because according to my plan I am
going to integrate it after login process in my website)
Yes you can customize your user flow. You can add new user flow according to yours.
To do that, Choose All services in the top-left corner of the Azure portal, and then search for and select Azure AD B2C
Then In the left menu, select User flows, and then select New user flow
See the screen shot below:
3. There are 3 types of account in Azure B2C, (Work account, Guest user, Consumer user), Which user type is most suitable? (I only need MFA for the user, and will require to manage users via Graph or any official API)
In short Work account has the more privileged in B2C tenant as the official document says. As consumer account cannot access some resource on portal. For accessing Microsoft Graph API Guest user has some restriction even on azure portal.
Note: As per your requirement I would suggest you to go with Work account which has some benefits while you would access Microsoft API
Though the account type mostly depend on your business needs but Work Account more useful comparing all aspect.
Let's say, If you want to add some user those who already registered some other organization but you need to add them in your particular application privilege. So need to add user as Guest privilege.
4. From where can I decide, which type of user will be registered?
Tough the question is bit confusing as I said earlier it would depend on your business needs. Work account usually best for tenant user. So when you feel within on your tenant if new user need to add so go with Work account. Once you specify your need it would definitely easier for you which kind of user you need to add. There is no such reference which can explain well upto to now.
Note: You could try adding all the user type to check how the user account behave using portal and accessing resources.
I'm using Azure AD B2C for my ASP.NET project. I want to use Multi-Factor authentication. Normally, after the sign-up, the user is redirected to the page to verify his phone number. I want to change this flow, I want to enable multi-factor if the user choose in a custom dropdown attribute 'Notifications' SMS, the other options are Email/No.
How can I redirect to this Multi-Factor page/Enable Multi-Factor depending on a value of a custom attribute.
Well, fortunately, the Azure B2C is quite a flexible tool and does exactly what you're asking for. You're free to define custom policies, attributes and user flows (this one is in preview state though). For your case, if you're the one who manages the tenant, go to B2C instance and select 'User flows (preview)' blade. Create a User attribute beforehand. Configure the flow as necessary. Complete configuration by running the user flow. More on the issue can be found in quite exhausting MS article here.
Is It possible to create a multi step sign up custom policy in azure ad b2c ?
I mean I need to capture personal details and verify them against my database if valid? Then second page to create a username and password and store them in azure active directory.
Since I already have a design implemented for these pages I don't want to change this by using ad b2c.
Please help.
Yes, this is possible, see the Wingtip sample for Azure AD B2C custom policies which contains a sign-up or sign-in policy that includes multiple orchestration steps.
You will have to validate the personal details via a REST API.
