Portal includes a built-in Microsoft authentication provider that uses Microsoft Azure Entra ID OAuth for user authentication. To enable Entra ID authentication for your Portal instance, follow these steps.
## Configure the Authentication Provider in Portal
1. From the admin sidebar section -> `App settings` -> `Auth` -> `Entra ID`.
2. Enter the following details from your Azure App Registration:
* `Client ID`
* `Tenant ID`
* `Client secret`
5. Below, select `Enable` under the `Use for Sign in` selector, then select `UserId matching user entity annotation` as resolver strategy.
6. Click Save.
## Test your new auth provider
To test your new auth provider, you can sign out of Portal and sign back in using your {props.providerName} credentials. If you are unable to sign in, please reach out to your organization's Portal admin for assistance.
To sign out follow these steps:
1. Select your profile from the sidebar
2. Press "Sign Out"
3. Sign back in using your Entra ID credentials
