v2 is built around Identity and UserProviderInterface.

It is not API-compatible with earlier 0.x (beta-era) releases. Treat upgrades as a rewrite; breaking changes are expected.

Installation

composer require "wscore/auth:^2.0"

Before v2 is tagged on Packagist, pin VCS / @dev / pre-release tags as needed.

Getting Started

Auth requires a UserProviderInterface (WScore\Auth\Contracts) implementation.

$auth = new Auth($userProvider);
$auth->setSession($session); // optional; default is active `$_SESSION` or an internal array

Password login (convenience):

use WScore\Auth\Auth;

if ($auth->loginWithPassword($id, $password)) {
    echo 'login success!';
}

Or with an Identity value object:

use WScore\Auth\Identity;

$ok = $auth->login(Identity::newPassword($id, $password));

// OAuth: provider user id (extract sub / id from raw responses in your bridge)
$ok = $auth->login(Identity::newOAuth('google', $googleUserId, [
    'email' => $email,
]));
// In UserProvider, read credentials[Identity::CREDENTIAL_PROVIDER_USER_ID]

Check login state:

$auth->isLogin();
$user = $auth->user();
$id = $auth->getLoginId();
$auth->getUserProvider(); // the UserProviderInterface instance

user() resolves in order: in-memory cache → session → remember-me cookie (if setRememberMe was configured).

Note: Calling isLogin() or user() may trigger an automatic login attempt via remember-me cookies if no active session exists. This can result in new cookies being sent or backend tokens being rotated.

$auth->logout(); // clears session segment, in-memory state, and remember-me cookies/tokens.

Timeouts

You can configure automatic logout based on the time elapsed since initial login (absolute timeout) or since the last access (activity timeout).

// Invalidate after 1 hour from initial login
$auth->setAbsoluteTimeout(3600);

// Invalidate after 15 minutes of inactivity
$auth->setActivityTimeout(900);

When a timeout is detected, logout() is automatically called during isLogin() or user().

AuthKind

getLoginInfo()['kind'] and isLoginBy() use WScore\Auth\AuthKind: Password, ForceLogin, OAuth, OneTimeToken, Remember.

Remember — the session was established via remember-me cookie validation (no password submitted on this login). This differs from password login with the “remember me” box checked, which stays Password.
Use isLoginBy(AuthKind::Remember) (or inspect getLoginInfo()['kind']) to distinguish that path from interactive logins.

Other Identity constructors: Identity::newForceLogin, Identity::newOneTimeToken, Identity::newRemember (for providers that resolve remember pairs in findByIdentity).

Force Login

use WScore\Auth\AuthKind;

$auth->forceLogin($id);
$auth->isLoginBy(AuthKind::ForceLogin);

getLoginInfo() includes kind (AuthKind), loginId, type (provider key), time.

UserProvider

Implement WScore\Auth\Contracts\UserProviderInterface:

findByIdentity(Identity $identity): ?object — resolve and verify credentials.
getUserId(object $user): string|int — id stored in session.
findById(string|int $userId): ?object — restore user from that id.
getProviderKey(): string — session segment key (namespaces Auth::KEY).

Remember-Me Option

Do not pass remember-me dependencies into the Auth constructor. Configure everything with setRememberMe() (e.g. after constructing Auth from a DI container factory).

RememberCookie handles HTTP cookies (id + token) and lifetime in days (default 7).

use WScore\Auth\RememberAdaptor\RememberCookie;

$auth = new Auth($userProvider, $session);

// Production: 30-day browser cookie (uses RememberCookie::forBrowser(30) internally)
$auth->setRememberMe($rememberMe, null, 30);

// Or pass an explicit RememberCookie
$auth->setRememberMe($rememberMe, RememberCookie::forBrowser(30));

// Tests: bag + replace setSetCookie
$bag = new \ArrayObject();
$cookie = new RememberCookie($bag, 7);
$cookie->setSetCookie($mockSetter);
$auth->setRememberMe($rememberMe, $cookie);

$rememberMe implements WScore\Auth\Contracts\RememberMeInterface. A PDO sample lives at WScore\Auth\RememberAdaptor\RememberMePdoSample (reference only—use your own in production). Call setRememberMe(null) to disable.

Advanced

setAuthSessionStore(WScore\Auth\Contracts\AuthSessionStoreInterface $store) — replace the default ArrayAuthSessionStore (e.g. integration tests or a non-array session backend).

Session Regeneration

By default, Auth::login() calls session_regenerate_id(true) for security (session fixation prevention). However, this can cause session loss on unstable networks or specific browser environments. You can disable this behavior if needed:

$auth->setRegenerateSessionOnLogin(false);

Enable on login:

$auth->loginWithPassword($id, $password, true);
// or Identity::newPassword($id, $password, ['remember' => true])
