What is Opauth?

Opauth provides a standardized interface between PHP applications and authentication providers.

Opauth as a framework provides a set of API that allows developers to create strategies that work in a predictable manner across PHP frameworks and applications.

Opauth works well with other PHP applications & frameworks.

Quick start

  1. Composer require Opauth core and Opauth strategies. Add the following to your application's composer.json:

        "minimum-stability": "dev",
        "require": {
            "opauth/opauth": "~1.0",
            "opauth/facebook": "~1.0"

    Note: While Opauth 1.0.x still is in development, your root composer.json will need to set its minimum-stability to dev.

    Install them

    $ composer install
  2. Configure Opauth.
    Create a file opauth.php that is accessible at http://localhost/opauth.php/.

    $config = array(
        'Strategy' => array(
            'Facebook' => array(
                'app_id' => 'YOUR APP ID',
                'app_secret' => 'YOUR APP SECRET'
        'path' => '/opauth.php/'
  3. Instantiate and run Opauth

    $Opauth = new Opauth\Opauth\Opauth($config);
    try {
        $response = $Opauth->run();
        echo "Authed as " . $response->name . " with uid" . $response->uid;
    } catch (OpauthException $e) {
        echo "Authentication error: " . $e->getMessage();
  4. Point your browser to http://localhost/opauth.php/facebook to see it in action.
