Azure AD B2C: Frequently asked questions (FAQ)

This page answers frequently asked questions about the Azure Active Directory B2C (Azure AD B2C). Keep checking back for updates.

Why can't I access the Azure AD B2C extension in the Azure portal?

There are two common reasons for why the Azure AD extension is not working for you. Azure AD B2C requires your user role in the directory to be global administrator. Please contact your administrator if you think you should have access. If you have global administrator privileges, make sure that you are in an Azure AD B2C directory and not an Azure Active Directory directory. You can see instructions for creating an Azure AD B2C tenant.

Can I use Azure AD B2C features in my existing, employee-based Azure AD tenant?

Azure AD and Azure AD B2C are separate product offerings and cannot coexist in the same tenant. An Azure AD tenant represents an organization. An Azure AD B2C tenant represents a collection of identities to be used with relying party applications. By adding New OpenID Connect provider under Azure AD B2C > Identity providers or with custom policies, Azure AD B2C can federate to Azure AD allowing authentication of employees in an organization.

Can I use Azure AD B2C to provide social login (Facebook and Google+) into Microsoft 365?

Azure AD B2C can't be used to authenticate users for Microsoft 365. Azure AD is Microsoft's solution for managing employee access to SaaS apps and it has features designed for this purpose such as licensing and Conditional Access. Azure AD B2C provides an identity and access management platform for building web and mobile applications. When Azure AD B2C is configured to federate to an Azure AD tenant, the Azure AD tenant manages employee access to applications that rely on Azure AD B2C.

What are local accounts in Azure AD B2C? How are they different from work or school accounts in Azure AD?

In an Azure AD tenant, users that belong to the tenant sign-in with an email address of the form <xyz>@<tenant domain>. The <tenant domain> is one of the verified domains in the tenant or the initial <...> domain. This type of account is a work or school account.

In an Azure AD B2C tenant, most apps want the user to sign-in with any arbitrary email address (for example,,,, or This type of account is a local account. We also support arbitrary user names as local accounts (for example, joe, bob, sarah, or jim). You can choose one of these two local account types when configuring identity providers for Azure AD B2C in the Azure portal. In your Azure AD B2C tenant, select Identity providers, select Local account, and then select Username.

User accounts for applications can be created through a sign-up user flow, sign-up or sign-in user flow, the Microsoft Graph API, or in the Azure portal.

Which social identity providers do you support now? Which ones do you plan to support in the future?

We currently support several social identity providers including Amazon, Facebook, GitHub (preview), Google, LinkedIn, Microsoft Account (MSA), QQ (preview), Twitter, WeChat (preview), and Weibo (preview). We evaluate adding support for other popular social identity providers based on customer demand.

Azure AD B2C also supports custom policies. Custom policies allow you to create your own policy for any identity provider that supports OpenID Connect or SAML. Get started with custom policies by checking out our custom policy starter pack.

Can I configure scopes to gather more information about consumers from various social identity providers?

No. The default scopes used for our supported set of social identity providers are:

  • Facebook: email
  • Google+: email
  • Microsoft account: openid email profile
  • Amazon: profile
  • LinkedIn: r_emailaddress, r_basicprofile

Does my application have to be run on Azure for it work with Azure AD B2C?

No, you can host your application anywhere (in the cloud or on-premises). All it needs to interact with Azure AD B2C is the ability to send and receive HTTP requests on publicly accessible endpoints.

I have multiple Azure AD B2C tenants. How can I manage them on the Azure portal?

Before opening 'Azure AD B2C' in the left side menu of the Azure portal, you must switch into the directory you want to manage. Switch directories by clicking your identity in the upper right of the Azure portal, then choose a directory in the drop down that appears.

How do I customize verification emails (the content and the "From:" field) sent by Azure AD B2C?

You can use the company branding feature to customize the content of verification emails. Specifically, these two elements of the email can be customized:

  • Banner logo: Shown at the bottom-right.

  • Background color: Shown at the top.

    Screenshot of a customized verification email

The email signature contains the Azure AD B2C tenant's name that you provided when you first created the Azure AD B2C tenant. You can change the name using these instructions:

  1. Sign in to the Azure portal as the Global Administrator.
  2. Open the Azure Active Directory blade.
  3. Click the Properties tab.
  4. Change the Name field.
  5. Click Save at the top of the page.

Currently you cannot change the "From:" field on the email.


With Azure AD B2C custom policy, you can customize the email Azure AD B2C sends to users, including the "From:" field on the email. The custom email verification requires the use of a third-party email provider like Mailjet, SendGrid, or SparkPost.

How can I migrate my existing user names, passwords, and profiles from my database to Azure AD B2C?

You can use the Microsoft Graph API to write your migration tool. See the User migration guide for details.

What password user flow is used for local accounts in Azure AD B2C?

The Azure AD B2C password user flow for local accounts is based on the policy for Azure AD. Azure AD B2C's sign-up, sign-up or sign-in and password reset user flows use the "strong" password strength and don't expire any passwords. For more details, see Password policies and restrictions in Azure Active Directory.

For information about account lockouts and passwords, see Mitigate credential attacks in Azure AD B2C.

Can I use Azure AD Connect to migrate consumer identities that are stored on my on-premises Active Directory to Azure AD B2C?

No, Azure AD Connect is not designed to work with Azure AD B2C. Consider using the Microsoft Graph API for user migration. See the User migration guide for details.

This feature is in public preview. For details, see Embedded sign-in experience.

Does Azure AD B2C work with CRM systems such as Microsoft Dynamics?

Integration with Microsoft Dynamics 365 Portal is available. See Configuring Dynamics 365 Portal to use Azure AD B2C for authentication.

Does Azure AD B2C work with SharePoint on-premises 2016 or earlier?

Azure AD B2C is not meant for the SharePoint external partner-sharing scenario; see Azure AD B2B instead.

Should I use Azure AD B2C or B2B to manage external identities?

Read Compare solutions for External Identities to learn more about applying the appropriate features to your external identity scenarios.

What reporting and auditing features does Azure AD B2C provide? Are they the same as in Azure AD Premium?

No, Azure AD B2C does not support the same set of reports as Azure AD Premium. However there are many commonalities:

  • Sign-in reports provide a record of each sign-in with reduced details.
  • Audit reports include both admin activity as well as application activity.
  • Usage reports include the number of users, number of logins, and volume of MFA.

Can end users use a time-based one-time password (TOTP) with an authenticator app to authenticate to my Azure AD B2C app?

Yes. End users need to download any authenticator app that supports TOTP verification, such as the Microsoft Authenticator app (recommended). For details see, verification methods.

Why are my TOTP authenticator app codes not working?

If the TOTP authenticator app codes aren't working with your Android or iPhone mobile phone or device, your device's clock time might be incorrect. In your device's settings, select the option to use the network-provided time or to set the time automatically. This feature is in public preview.

I have revoked the refresh token using Microsoft Graph invalidateAllRefreshTokens, or Azure AD PowerShell, Revoke-AzureADUserAllRefreshToken. Why is Azure AD B2C still accepting the old refresh token?

In Azure AD B2C, if the time difference between refreshTokensValidFromDateTime and refreshTokenIssuedTime is less than or equal to 5 minutes, the refresh token is still considered as valid. However, if the refreshTokenIssuedTime is greater than the refreshTokensValidFromDateTime, then the refresh token is revoked. Follow the following steps to check if the refresh token is valid or revoked:

  1. Retrieve the RefreshToken and the AccessToken by redeeming authorization_code.

  2. Wait for 7 minutes.

  3. Use PowerShell cmdlet Revoke-AzureADUserAllRefreshToken or Microsoft Graph API invalidateAllRefreshTokens to run the RevokeAllRefreshToken command.

  4. Wait for 10 minutes.

  5. Retrieve the RefreshToken again.
