}
catch(\Exception $ex) {
    printf('DB Error creating user: %s', $ex->getMessage());
}

# login user
try {
    $user = $auth->login('username', 'password');
}
catch(PasswordMismatchException $ex) {
    printf("Password mismatch");
}
catch(UserException $ex) {
    printf("Error logging in: %s", $ex->getMessage());
}

# check if the user is logged in
if($auth->check()) {
    // user is logged in
}
else {
    // user is not logged in
};

# retrieve the current user from the session
try {
    $user = $auth->user();
}
catch(UserException $ex) {
    printf("User not logged in");
}

# logout user
$auth->logout();

Store additional data when registering a user

$user = $auth->register('username', 'password', [
    'email' => 'someone@somewhere',
    'displayName' => 'Test User'
]);

Generating a password reset token

When the token parameter is enabled in initialization

$token = $auth->update_token($username);

// send $token to user, then later
try {
    $auth->passwd_reset($token, $new_password);
}
catch(UserException $ex) {
    printf('Invalid token provided');
}

Updating user data

$auth->update($username, [ 'email' => '[email protected]' ]);
