Authenticaton classes


Install using composer

composer require sinevia/php-library-authentication


1. Identity management

The Authentication class helps you reliably keep the authenticated users during the current session.

\Sinevia\Authentication::getInstance()->setIdentity('user', $loggedinUser->Id); // After successful login
$userId = \Sinevia\Authentication::getInstance()->getIdentity('user'); // During session
\Sinevia\Authentication::getInstance()->reoveIdentity('user'); // On logout

2. Namespaced Identities

Probably the greatest features is the support of namespaces. The namespaces allows to keep separation betweern different areas of responsibility. The following example will help illustrate the namespaces better. A website may be separated into manager area, clients area, employee area, each with different functions. Upon login a manager can be set to authenticated both as a manager and employee (example 1). Upon attempting to access the area his access can be checked before being allowed/denied to continue (example 2).

Example 1. Add the current user both to the manager and employee namespace

if ($isManager) {
    \Sinevia\Authentication::getInstance()->setIdentity('manager', $loggedinUser->Id);
if ($isEmployee) {
    \Sinevia\Authentication::getInstance()->setIdentity('employee', $loggedinUser->Id);

Example 2. Check if user is allowed access to the manager area and allow/deny access

// Check if the user is part of the manager namespace
$managerId = \Sinevia\Authentication::getInstance()->getIdentity('manager');

// Check if user cannot access the manager access
$cannotAccessManagerArea = is_null($managerId);

// Deny access to manager area
if (cannotAccessManagerArea) {
    die('Only managers are allowed access to the manager area');

In practice you may like to create a helper class to help with keeping the authentication process more readable

class Auth {

     * Returns the user authenticated to a namespace
     * @param string $namespace
     * @return \App\Models\Users\User
    public static function getUser($namespace) {
        return \Sinevia\Authentication::getInstance()->getIdentity($namespace);

     * Sets the authenticated user to a namespace
     * @param string $namespace
     * @param \App\Models\Users\User $user
     * @return void
    public static function setUser($namespace, $user) {
        return \Sinevia\Authentication::getInstance()->setIdentity($namespace, $user);

     * Removes the user from a namespace
     * @param string $namespace
     * @return void
    public static function removeUser($namespace) {
        return \Sinevia\Authentication::getInstance()->emptyIdentity($namespace);

Then use it like:

$managerId = Auth::getUser('manager');
