# React Native apps can use hosted sign-in

> Developers can add hosted member sign-in to React Native and Expo apps without running a callback website.

# React Native apps can use hosted sign-in

Developer Access now includes **Add React Native app**. Enter the application
ID with `.thefaithapp` appended, and TheFaithApp creates the matching mobile
callback automatically.

The React Native SDK opens hosted member sign-in, returns a bearer token, saves
the member session securely, and sends authenticated `v1` API requests. Its
Expo config plugin adds the callback to the generated iOS and Android projects.

The API Reference includes a complete React Native and Expo quickstart covering
installation, callback registration, native builds, sign-in, API requests,
session restoration, and logout.

Current-member responses now include only the public church context apps need.
