 Authentication in Blazor Hybrid apps is handled by native platform libraries, as they offer enhanced security guarantees that the browser sandbox can't offer. Authentication of native apps uses an OS-specific mechanism or via a federated protocol, such as [OpenID Connect (OIDC)](https://openid.net/connect/). Follow the guidance for the identity provider that you've selected for the app and then further integrate identity with Blazor using the guidance in this article.
