Steps to configure Microsoft Teams Single Sign-On (SSO) Login into WordPress

1. Setup Microsoft Teams as OAuth Provider

• Sign in to Azure portal.

• In the left-hand navigation pane, click the App registrations service, and click New registration.

• When the Create page appears, enter your application's registration information.(Refer to the below table)

Name :	Name of your application.
Application type :	Select "Web app / API" for client applications and resource/API applications that are installed on a secure server. This setting is used for OAuth confidential web clients and public user-agent-based clients. The same application can also expose both a client and resource/API.
Redirect URI :	For "Web app / API" applications, provide the base URL of your app. eg, https://<domain-name> might be the URL for a web app running on your local machine. Users would use this URL to sign in to a web client application.

• Make sure the "Grant admin consent to openid and offline_access permissions" option is enabled. When finished, click Register.

• Azure AD assigns a unique Application ID to your application. The Application ID is your Client ID and the Directory ID is your Tenant ID, keep these values handy as you will need them to configure the miniOrange OAuth Client plugin.
