React Hooks for Expo Native

Add authentication to your Native application faster with Clerk’s React hooks. Maintain control of your UI while Clerk handles the complexities of user management, authentication, session handling, and more.

export default function Page() {
  const { signIn, setActive } = useSignIn()

  const handleSubmit = ({ emailAddress, password }) => {
    signIn.create({ identifier: emailAddress, password })
      .then(async ({ createdSessionId }) => {
        await setActive({ session: createdSessionId })
        router.replace('/')
      })
  }

  return <YourCustomForm onSubmit={handleSubmit} />
}

Components for Expo Web

Add sign-in, sign-up, user management, and more to your Web application with drop-in components that work out of the box and are easy to customize.

<SignIn />

It all starts here. Configure your <SignIn /> component with authentication options your users find convenient then embed it directly in your application.

Authentication options you want, configured with a single click

No more wrestling with deep links and platform-specific quirks. Clerk provides the quickest way to authenticate and secure your Expo users.

Social sign-on

Clerk handles the browser-based OAuth flows for you, including deep linking back into your Expo app after authentication.

Passkeys

Add passkeys to your application to provide a modern, passwordless sign-in experience that enhances your security and allows you to authenticate faster.

Multi-factor authentication

Add an extra layer of security with built-in support for multi-factor authentication using TOTP or SMS/email codes.

Local credentials Beta

Save a user’s password on their device after the first sign-in, then allow future logins with biometrics like Face ID, reducing friction for returning users.

Hooks and helper components to control access to your app

Fine-tune which screens and features your users can access based on their identity, permissions, or role.

Protect your screens

Use Clerk’s control components like <SignedIn />, <SignedOut />, and <RedirectToSignIn /> to secure your screens and redirect unauthenticated users.

import { SignedIn, SignedOut } from '@clerk/expo'
import { Text, View } from 'react-native'

const ProtectedPage = ({ children }) => {
  return (
    <View>
      <SignedIn>
        <Text>You are signed in</Text>
      </SignedIn>

      <SignedOut>
        <Text>You are signed out</Text>
      </SignedOut>
    </View>
  )
}

export default ProtectedPage

Role-based access control

Define and assign permissions from the Clerk dashboard then conditionally render components based on the user’s access rights.

import { Protect } from '@clerk/clerk-expo'
import { Text } from 'react-native'

const ProtectedPage = ({ children }) => {
  return (
    <Protect
      permission="org:invoices:create"
      fallback={
        <Text>You don’t have permission.</Text>
      }
    >
      {children}
    </Protect>
  )
}

export default ProtectedPage

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.

Customize session lifetime

Configure the session lifetime from 5 minutes to 10 years, with an optional inactivity timeout.

Encrypted local token storage

Encrypt and store authentication tokens using Expo SecureStore, ensuring tokens are protected at the device level.

Mobile offline support Beta

Clerk keeps Native users signed in without an internet connection. Access cached user data even when the device is offline.
