Azure Active Directory


Azure Active Directory returns the following fields on Account:

  • token_type (string)
  • expires_in (number)
  • ext_expires_in (number)
  • access_token (string).

Remember to add these fields to your database schema, in case if you are using an Adapter.




To allow specific Active Directory users access:

  • In search for "Azure Active Directory", and select your organization.
  • Next, go to "App Registration" in the left menu, and create a new one.
  • Pay close attention to "Who can use this application or access this API?"
    • This allows you to scope access to specific types of user accounts
    • Only your tenant, all azure tenants, or all azure tenants and public Microsoft accounts (Skype, Xbox,, etc.)
  • When asked for a redirection URL, select the platform type "Web" and use or for development http://localhost:3000/api/auth/callback/azure-ad.
  • After your App Registration is created, under "Client Credential" create your Client secret.
  • Now copy your:
    • Application (client) ID
    • Directory (tenant) ID
    • Client secret (value)

In .env.local create the following entries:

AZURE_AD_CLIENT_ID=<copy Application (client) ID here>
AZURE_AD_CLIENT_SECRET=<copy generated client secret value here>
AZURE_AD_TENANT_ID=<copy the tenant id here>

That will default the tenant to use the common authorization endpoint. For more details see here.

When you see ResourceNotFound error code while accessing an API, make sure to use the correct tenant ID. For instance, when the intended access is for a personal account, the tenant ID should not be provided. :::


Azure AD returns the profile picture in an ArrayBuffer, instead of just a URL to the image, so our provider converts it to a base64 encoded image string and returns that instead. See: The default image size is 48x48 to avoid running out of space in case the session is saved as a JWT.

In pages/api/auth/[...nextauth].js find or add the AzureAD entries:

import AzureADProvider from "next-auth/providers/azure-ad";

providers: [
clientId: process.env.AZURE_AD_CLIENT_ID,
clientSecret: process.env.AZURE_AD_CLIENT_SECRET,
tenantId: process.env.AZURE_AD_TENANT_ID,
