How to Use Clerk's AuthView in an Expo App

Mobile authentication in app development traditionally requires either building custom sign-in flows with extensive coding or using WebView-based components that disrupt the native user experience. However, Clerk's AuthView component simplifies this process by providing a fully native authentication UI with minimal code, enhancing both security and user experience. This tutorial guides developers through building an Expo app featuring native sign-in and sign-up using AuthView, which leverages SwiftUI on iOS and Jetpack Compose on Android, ensuring a genuinely native user interface. AuthView, released in March 2026, supports various authentication methods configured via the Clerk Dashboard, such as email, password, OAuth providers, and multi-factor authentication, without needing code changes for updates. The tutorial highlights the advantages of native authentication over WebView-based methods, including compliance with OAuth 2.0 standards and improved conversion rates due to reduced user friction. Furthermore, it addresses common issues and troubleshooting steps, emphasizing the need for a development build rather than Expo Go, due to AuthView's reliance on native modules.
