Expo can be used to login to many popular providers on Android, iOS, and web. [`expo-auth-session`](/versions/latest/sdk/auth-session/) package allows [browser-based authentication](/versions/latest/sdk/auth-session/#how-web-browser-based-authentication-flows-work) (using OAuth or OpenID Connect) to your project for Android, iOS, and the web. You can also implement authentication using native libraries for third-party providers with [development builds](/develop/development-builds/create-a-build).
