Native Expo authentication
Clerk’s Expo SDK provides drop-in native UI components for sign-in, sign-up, and user management, built from SwiftUI on iOS and Jetpack Compose on Android.
Social sign-on
Support a range of SSO providers, including native Google Sign-In, to give your users a faster and more secure sign-in experience
Passkeys
Enable your users to sign in using biometrics, like a fingerprint or face scan, instead of a password.
Multi-factor authentication
Offer multi-factor authentication options, including time-based one-time passwords (TOTP) and backup codes.
Local credentials
The useLocalCredentials() hook enables you to store a user’s password on device and subsequently use biometrics for sign-in.
Clerk handles the session, even if the user is offline
Keep your users authenticated and engaged, even in challenging network conditions, without writing any session management code.
Configurable session lifetime
Set session duration from 5 minutes to 10 years, with an optional inactivity timeout.
Encrypted local token storage
Authentication tokens are encrypted and stored using expo-secure-store, protected at the device level.
Mobile offline support
Keep users signed in without an internet connection. Cached user data stays accessible when the device is offline.
Advanced security and privacy
Ship fast, stay secure
Clerk is regularly audited and certified by industry-leading third-party standards.
Secure, private, and compliant. Always.
