3. In the left menu, select [**App registrations**](https://portal.azure.com/#view/Microsoft_AAD_IAM/ActiveDirectoryMenuBlade/~/RegisteredApps), click **New registration**.
4. Open the RustDesk Pro console, in the **Settings** page, click the **OIDC** module. Then copy the **Callback URL**. **Note**: The **Callback URL** is not editable, the `Path` part is fixed to `api/oidc/callback`, and the `Protocol://Host:Port` part is the origin of the current web page. If you open it through the address `http://localhost:8000/<path>`, then the **Callback URL** is `http://localhost:8000/api/oidc/callback`. If you open it through the address `https://192.168.0.1:8000/<path>` is opened, then the **Callback URL** is `https://192.168.0.1:8000/api/oidc/callback`. Because Azure must use `https://` or `http://localhost`, please select the appropriate address to open your RustDesk Pro console.
10. In Azure, copy the value of the client secret. **Note**: This value is only visible when you first register. It is no longer visible after you leave the page. Please keep this value properly.
12. In RustDesk Pro, fill in the **Issuer** field with `https://login.microsoftonline.com/<Directory (tenant) ID>/v2.0`. Please replace `Directory (tenant) ID` with your **Directory (tenant) ID**. The **Directory (tenant) ID** is in Azure's app **Overview** panel.
