Today we announce the public preview of Microsoft Entra External ID as an identity provider for Microsoft Power Pages—simplifying authentication for your external-facing apps so that you can focus on building features.
A lot of time can be spent on development when building a website, especially when it comes to figuring out how to authenticate users. Power Pages enables you to get a website up and running within a few minutes, while External ID offers a wide range of resources to secure external identities with extensive customization capabilities. Offering out-of-the-box authentication, External ID enables you to save significant time and effort, allowing you to focus on the rest of the application.
Advantages of using External ID include:
- Enhanced security: Businesses can ensure secure access for their users, protecting sensitive information and reducing the risk of unauthorized access.
- Improved user experience: A streamlined authentication process reduces complexity for users, providing a smoother and more intuitive experience.
- Scalability: The ability to handle large numbers of users and various identity providers makes this integration ideal for businesses of all sizes.
In this blog post, I show you how to set up and run External ID with a Power Pages demo website.
Prerequisites
- An external tenant on Microsoft Entra Admin Center.
- If you don’t have one, you can create one using our 30-day free trial or create an external tenant with an Azure subscription.
- Ensure you have the Application Administrator role and External ID User Flow Administrator role on Microsoft Entra.
- A Power Pages environment or sign up for a 30-day free Power Pages trial. You’ll need either a system administrator or a read-write user account.
- A demo site with a sign-up process (you can use the starter layout 1 template from the list of Power Pages templates, which is the one used here).
Set up External ID on your website
- Log in to Power Pages and click Edit on the site where you want to configure an External ID provider.
- Click on Security, then click Configure beside Microsoft Entra External ID.
- A guided wizard will pop up prompting you to enter configuration details.
- Select your provider.
- Select ‘Microsoft Entra External ID’ as your log in provider.
- The provider’s name is the label that will appear on the sign-in button. It can be something simple like ‘Microsoft Entra External ID’ or ‘Log in with External ID’.
- Click Next.
- Register your application in the Microsoft Entra Admin Center.
- Go to the Microsoft Entra Admin Center.
- Click on App registrations > New registration.
- Enter a name for your app. For example, ‘power-pages-app’. Select ‘Web’ as your platform and copy the reply URL from Power Pages and paste it in the redirect URL field in the Microsoft Entra Admin Center.
- Click Register.
- On the power-pages-app Authentication tab, select ‘Access tokens’ and ‘ID tokens’ and click Save.
- On the API permissions tab, grant ‘admin’ consent.
- Create a user flow.
- Navigate to External Identities > User flows.
- Click create New user flow.
- Give the user flow a name, e.g. ‘Power-pages-user-flow’ and select ’email with password’. Click Create.
- Link application to the user flow.
- On the user flow you just created (power-pages-user-flow), click Applications > Add application. Select your application, in this case it is ‘power-pages-app’, and click Select.
- Configure site settings.
- Go to Applications > App registrations > All applications and select ‘power-pages-app’.

- Under Site Actions, click on Restart site. A confirmation dialog box will appear. Click Restart. It will take a few minutes to complete and for the changes to be reflected on your site.
- Open your site URL and head over to the sign- in page. The button you configured in step 2, ‘Microsoft Entra External ID’, will now be visible. Click on it.
- Sign up a new user with the sign-up flow.
- At the end of the user flow, you will be directed to complete the registration on the website. Enter the same email address and click Register.
