Passkey Authentication

Register or login a user using passkeys in React Native

Register a new user with a passkey

To create a new user account with a passkey, provide the user’s email address or phone number to Passage.registerWithPasskey(). View a full registration implementation on Github.

const passage = new Passage('APP_ID');

const register = async (identifier: string) => {
  try {
    
    // Register user 
    await passage.registerWithPasskey(identifier);
    
    // Retrieve new user info
    const user = await passage.getCurrentUser();
  } catch (error) {
    if (error instanceof PassageError && error.code === PassageErrorCode.UserCancelled) {
      // User cancelled native passkey prompt
    } else {
      // Optional: Passkey registration failed, try email or SMS registration instead.
    }
  }
};

Log in an existing user with a passkey

To authenticate an existing user with their passkey, pass the user’s email address or phone number to Passage.loginWithPasskey(). View a full registration implementation on Github.

  const login = async (identifier: string) => {
    try {

      // Login user
      await passage.loginWithPasskey();
      
      // Retrieve logged in user info
      const user = await passage.getCurrentUser();
      setCurrentUser(user);
    } catch (error) {
      if (error instanceof PassageError && error.code === PassageErrorCode.UserCancelled) {
        // User cancelled native passkey prompt
      } else {
        if (identifier.length) {
          
          // Optional: Passkey login failed, try fallback email or SMS login instead.
        }
      }
    }
  };
