- Open Microsoft Entra and log in with your Microsoft 365 admin account.
- If you have more than one directory, expand the correct directory.
- Click Applications > App registrations in the side navigation bar.
- In the top menu, click ➕New Registration.
- Enter a display name for the application. This will be shown to users.
- Select a set of users who will have access to the application:
- Accounts in this organizational directory only (MSFT only - Single tenant): Only people who have a user or guest account in your Microsoft Entra can use your application.
- Accounts in any organizational directory (Any Microsoft Entra ID directory - Multitenant): Anyone who has a work or school Microsoft account can use your application. This excludes personal Microsoft accounts. Also enables multitenancy for your application.
- Accounts in any organizational directory (Any Microsoft Entra ID directory - Multitenant) and personal Microsoft accounts (e.g. Skype, Xbox): Anyone who has a personal, work, or school Microsoft account can use your application. Use this option to target the widest set of Microsoft accounts. Also enables multitenancy for your application.
- Personal Microsoft accounts only: Anyone with a personal Microsoft account – for example, who signs in to services like Xbox – can use your application.
Note: Changing this access setting after you’ve registered the application can cause errors.
- Select the platform and enter a URL for users to be redirected to after they log in.
- Click Register.
Entra will display the application in the Owned applications tab of the App registrations page. You will need to copy the Application (client) ID and the Directory (tenant) ID to provide to AARNet later in the process.
