How To Set Up Your Own Microsoft App (OpenID Connect)

Last updated 08/04/2025

Step 1

https://portal.azure.com/

Step 2

Under Azure services, click on App registrations.

If you don't see it, click on "more services" and search for it.

Step 3

Click New Registration.

Step 4

Enter a name for your application (we recommend using your organization name).
Select Single Tenant for the supported account types.
Set the Redirect URI to Web, then enter:

https://api.breadbutter.io/callback

Note: For the Microsoft Enterprise Provider, please ensure that the account type is Single Tenant. This restricts login to your domain only, whereas "Multitenant" will allow any Microsoft user to log in.

Step 5

Click Register.
After the application is created, copy and save the Application (client) ID for the last step.

Step 6

Click on Endpoints at the top of the page, and copy the following for the last step:
- OAuth 2.0 authorization endpoint (v2)
- OAuth 2.0 token endpoint (v2)

Step 7

In the left menu under Manage click on Certificates & Secrets, and then click on New client secret.
Enter a description, set your desired expiry, and then click Add.
Set a reminder for yourself to replace this Secret before it expires. If the Secret expires, your users will no longer be able to log in with the provider.

Step 8

Copy and store the Secret Value immediately. If you navigate away, the value will no longer be visible and you will have to generate a new secret.

Step 9

In the left menu, click on Branding & properties. Then enter your Privacy Policy URL, Terms of service URL, and any other branding options you would like.

Step 10

On the same page, add your MPN ID (sometimes called Partner ID) to verify the publisher.
For more information on joining, check out Microsoft's Partner Program.
Note: You can come back and complete this step later, but your app will show as "Unverified" to your users.
