Follow these steps carefully to connect your Bubble app to Microsoft.
🟢 PART 1: Microsoft Azure Setup

Go to the Azure Portal and log in.

Search for and select App registrations, then click + New registration.

Name: Enter your app's name.

Supported account types: Select the 3rd option: "Accounts in any organizational directory and personal Microsoft accounts". (Crucial for allowing both business and personal emails!).

Redirect URI: Select Web. Paste your Bubble app's Redirect URI.

⚠️ IMPORTANT: Microsoft does NOT allow query strings (like ?debug_mode=true or ?tab=tabs-3). Ensure you paste a clean URL (e.g., https://your-app.bubbleapps.io/api/1.1/oauth_redirect).

Click Register.

In the Overview page, copy the Application (client) ID.

Go to Certificates & secrets (left menu) > + New client secret. Name it and click Add.

CRITICAL: Copy the string in the Value column immediately (do NOT copy the Secret ID). Microsoft hides this value once you leave the page!

🔵 PART 2: Bubble Setup

Install this plugin in your Bubble app.

Paste the Application (client) ID into the App ID field.

Paste the Secret Value into the App Secret field.

Add a button to your page (e.g., "Login with Microsoft").

Add a Workflow: Account -> Signup/login with a social network -> Select Microsoft Login.

Bonus (Get User Name): To get the user's full name, add a second workflow action: Data (Things) -> Make changes to Current User. Change their Name field by selecting Get data from an external API -> Microsoft Login - Get User Profile -> 's displayName.
