Passkey Authentication
Register or log in a user using passkeys in Flutter
To create a new user account with a passkey, provide the user’s email address or phone number to
passage.register(). View a full registration implementation on GitHub.final passage = PassageFlutter();
void register(String identifier) async {
try {
// Register user
await passage.register(identifier);
// Retrieve new authenticated user info
final PassageUser user = await passage.getCurrentUser();
} catch (error) {
if (error is PassageError &&
error.code == PassageErrorCode.userCancelled) {
// User cancelled passkey prompt, do nothing.
} else {
// Optionally try an email or sms registration method (see next page)
}
}
}
To authenticate an existing user with their passkey, use
passage.login or passage.loginWithIdentifier (depending on platform). View a full registration implementation on GitHub.void login(String identifier) async {
try {
if (kIsWeb) {
// Web log in requires an email or phone for logging in
await passage.loginWithIdentifier(identifier);
} else {
// iOS and Android do not accept an identifier.
// These platforms will simply show any user passkeys associated with your app.
await passage.login();
}
// Retrieve authenticated user info
final PassageUser user = await passage.getCurrentUser();
} catch (error) {
if (error is PassageError &&
error.code == PassageErrorCode.userCancelled) {
// User cancelled passkey prompt, do nothing.
} else {
// Optionally try an email or login method (see next page)
}
}
}
