Two-factor & passkeys

Setting up factors during login is covered in Login challenges. This page covers a signed-in account managing its own factors. The ceremonies belong to two-factor-for-laravel and passkeys-for-laravel; this package adds guard modes, re-authentication, invalidation, events and notifications.

Two-factor (TOTP + recovery codes)

Available when the guard’s two_factor.mode is not off:

From PHP, the twoFactor() sub-context runs the same steps — pass the caller’s $current token to keep its device and get the re-issued pair:

use RoundlyConsulting\Auth\Facades\Authentication;

$twoFactor = Authentication::guard('users')->twoFactor();

$status = $twoFactor->status($user);      // enabled, pending, recoveryCodesRemaining, mode
$setup  = $twoFactor->start($user);       // show $setup->qrSvg / ->secret, store ->recoveryCodes
$tokens = $twoFactor->confirm($user, $code, $current, $context);

$codes  = $twoFactor->regenerateRecoveryCodes($user, $current, $context);   // codes, tokens
$tokens = $twoFactor->disable($user, $current, $context);

• Starting while already enabled answers two_factor_already_enabled (409); qr_svg is null when two_factor.qr.enabled is off or rendering failed.
• A wrong or stale confirmation code answers invalid_code (422); disabling under required answers two_factor_required (409).
• Confirm, regenerate and disable apply invalidation.two_factor_changed (default others): every other session ends and the caller gets a fresh pair — swap immediately.
• Events TwoFactorEnabled, TwoFactorDisabled and RecoveryCodesRegenerated; using a recovery code at login fires RecoveryCodeUsed and mails the remaining count.

Passkeys

Available when the guard’s passkeys.mode is not off:

From PHP, through the passkeys() sub-context — rename() and remove() take a Passkey or its id, and another account’s passkey is PasskeyNotFound:

use RoundlyConsulting\Auth\Facades\Authentication;

$passkeys = Authentication::guard('users')->passkeys();

$options = $passkeys->registrationOptions($user);                          // ceremonyId + publicKey
$added   = $passkeys->register($user, $response, 'MacBook', $current, $context);   // passkey, tokens

$passkeys->all($user);                                                     // newest first
$passkeys->rename($user, $passkeyId, 'Work laptop');                       // a Passkey or its id
$tokens = $passkeys->remove($user, $passkeyId, $current, $context);

• A failed attestation answers passkey_registration_failed (422); names are sanitised.
• Removing the last passkey is refused with last_credential (409) when the account would have no other way in, or the guard requires passkeys.
• Register and remove apply invalidation.passkey_changed (default none, so tokens is null) and fire PasskeyAdded / PasskeyRemoved.
