Radically Simple.

It only takes one line of code.

useSignIn()

The useSignIn() hook gives you access to the SignIn object inside your components. You can use the methods of the SignIn object to create your own custom sign in flow, as an alternative to using Clerk's pre-built <SignIn/> component.

import { useClerk, useSignIn } from "@clerk/clerk-expo"
  ...
  const { setSession } = useClerk();
  const signIn = useSignIn();
  ...

  const onSignInPress = async () => {
    try {
      const completeSignIn = await signIn.create({
        identifier: emailAddress,
        password,
      });

    await setSession(completeSignIn.createdSessionId);
  ...

useUser()

The useUser() hook accesses the active User object. It can be used to update the user or display information about the user's profile, like their name or email address. The hook provides a shortcut for retrieving the Clerk.session.user property.

import { useClerk, useUser } from '@clerk/clerk-expo';
  ...
    const { signOut } = useClerk();
    const { firstName } = useUser();
  
    return (
      <View style={styles.container}>
        <Avatar.Image size={100} source={avatar} />
        <Text style={styles.title}>
          Hello, {firstName}!
        </Text>
        <Button 
          style={styles.link} 
          mode="text" 
          onPress={onSignOutPress}>
            Sign out
        </Button>
      </View>
    );
...
