Azure Active Directory Verifiable Credentials is now Microsoft Entra Verified ID and part of the Microsoft Entra family of products. Learn more about the Microsoft Entra family of identity solutions and get started in the unified Microsoft Entra admin center.

In this guide, you'll create a credential where the claims come from a user profile in the directory of the Azure AD tenant. With directory based claims you can create Verifiable Credentials of type VerifiedEmployee, if the users in the directory are employees.

In this article, you learn how to:

  • Create a user in the directory
  • Setup the user for Microsoft Authenticator
  • Create a Verified employee credential
  • Configure the samples to issue and verify your VerifiedEmployee credential

Prerequisites

Create a user in the directory

If you already have a test user, you can skip this section. If you want to create a test user, follow the steps below:

  1. As an User Admin, navigate to the Azure Active Directory in the Azure portal
  2. Select Users and + New user, then keep selection on [x] Create user
  3. Fill in User name, Name, First name and Last name.
  4. Check [x] Show Password and copy the temporary password to somewhere, like Notepad, then select the Create button
  5. Find the new user, select to view profile and select Edit. Update the following attributes then select Save:
    • Job Title
    • Email (in the Contact Info section. Doesn't have to be an existing email address)
    • Photo (select JPG file with low, thumbnail like, resolution. Maximum size is 2MB.)
  6. Open a new, private, browser window and navigate to page like https://myapps.microsoft.com/ and sign in with your new user. The user name would be something like meganb@yourtenant.onmicrosoft.com. You'll be prompted to change your password

Set up the user for Microsoft Authenticator

Your test user needs to have Microsoft Authenticator setup for the account. To enable Authenticator on the test user account, follow these steps:

  1. On your mobile test device, open Microsoft Authenticator, go to the Authenticator tab at the bottom and tap + sign to Add account. Select Work or school account
  2. At the prompt, select Sign in. Don't select “Scan QR code”
  3. Sign in with the test user’s credentials in the Azure AD tenant
  4. Authenticator will launch https://aka.ms/mfasetup in the browser on your mobile device. need to sign in again with your test users credentials.
  5. In the Set up your account in the app, select Pair your account to the app by clicking this link. The Microsoft Authenticator app and opens and you see your test user as an added account

If https://aka.ms/mfasetup launches without prompting you to sign in, that means you have already set up authenticator for another user on this device. When already configured with a user, Authenticator signs you in automatically. Sign out the browser's currently logged in user and then repeat the steps above. If you zoom in on the page, you find the Sign out button at the top right corner

Create a Verified employee credential

When you select + Add credential in the portal, you get the option to launch two Quickstarts. Select Verified employee and select Next.

Quickstart start screen

In the next screen, you enter some of the Display definitions, like logo url, text and background color. Since the credential is a managed credential with directory based claims, rules definitions are predefined. You don't need to enter rule definition details. The credential type will be VerifiedEmployee and the claims from the user’s profile are pre-set. Select Create to create the credential.

Claims schema for Verified employee credential

All of the claims in the Verified employee credential come from attributes in the user's profile in Azure AD for the issuing tenant. All claims, except photo, come from the Microsoft Graph Query https://graph.microsoft.com/v1.0/me. The photo claim comes from the value returned from the Microsoft Graph Query https://graph.microsoft.com/v1.0/me/photo/$value.

Claim Directory attribute Value
revocationId userPrincipalName The UPN of the user is added as a claim named revocationId and gets indexed.
displayName displayName The displayName of the user
givenName givenName First name of the user
surname surname Last name of the user
jobTitle jobTitle The user's job title. This attribute doesn't have a value by default in the user's profile. If the user's profile has no value specified, there's no jobTitle claim in the issued VC.
preferredLanguage preferredLanguage Should follow ISO 639-1 and contain a value like en-us. There's no default value specified. If there's no value, no claim is included in the issued VC.
mail mail The user's email address. The mail value isn't the same as the UPN. It's also an attribute that doesn't have a value by default.
photo photo The uploaded photo for the user. The image type should be JPEG and the maximum size is 2MB. When presenting the photo claim to a verifier, the photo claim is in the UrlEncode(Base64Encode(photo)) format. To use the photo, the verifier application has to Base64Decode(UrlDecode(photo)).

See full Azure AD user profile properties reference.

If attribute values change in the user's Azure AD profile, the VC isn't automatically reissued. You must reissue it manually. Issuance would be the same as the issuance process when working with the samples.

Configure the samples to issue and verify your VerifiedEmployee credential

Verifiable Credentials for directory based claims can be issued and verified just like any other credentials you create. All you need is your issuer DID for your tenant, the credential type and the manifest url to your credential. The easiest way to find these values for a Managed Credential is to view the credential in the portal, select Issue credential and you will get a header named Custom issue. These steps bring up a textbox with a skeleton JSON payload for the Request Service API.

Custom issue

In this screen, you have values that you can copy and paste to your sample deployment’s configuration files. Issuer’s DID is the authority value.

  • authority - Issuer's DID
  • type - the credential type is always VerifiedEmployee when looking at a verified employee credential
  • manifest - the credential manifest URL

The configuration file depends on the sample in-use.

Remarks

Note

This schema is fixed and it is not supported to add or remove claims in the schema. The attestation flow for directory based claims is also fixed and it is unsupported to try and change it to become a custom credential with id token hint attestation flow, for example.
