Opauth

Opauth is a multi-provider authentication framework for PHP, inspired by OmniAuth for Ruby.

Opauth enables PHP applications to do user authentication with ease.

Try out Opauth for yourself at http://opauth.org

Build Status

What is Opauth?

Opauth provides a standardized method for PHP applications to interface with 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. It is currently supported on:

If your PHP framework of choice is not yet listed, you can still use Opauth like you would a normal PHP component (class).

Quick start

Guide on how to run the bundled example.

  1. Set DocumentRoot of your web server to example/.
    (Opauth can be instantiated in your own PHP app, but we will leave that out of this quick start guide)

  2. Configure Opauth.

    First, make a copy of opauth config's file by copying or renaming
    opauth.conf.php.default to opauth.conf.php.

    Open up opauth.conf.php and make the necessary changes.

  3. Install some Opauth strategies.
    Place the strategy files in lib/Opauth/Strategy/.

    For this example, we recommend that you start with Opauth-Facebook:

    i. Download the strategy files and place them at lib/Opauth/Strategy/Facebook/.

    ii. Follow the steps at Opauth-Facebook's README to set up your Faceobok app.

    iii. Add the following at opauth.conf.php under Strategy as such:

<?php
'Strategy' => array(  
    // Define strategies here.

    'Facebook' => array(
        'app_id' => 'YOUR APP ID',
        'app_secret' => 'YOUR APP SECRET'
    ),
);

Finally, send user to http://localhost/facebook to authenticate.

Check out the wiki for more in-depth details, especially on how to use Opauth with your own PHP application.

Available strategies

A strategy is a set of instructions that interfaces with respective authentication providers and relays it back to Opauth.
