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(identifier);
// 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.
}
}
}
};
