This module depends on Opauth which is no longer maintained - we don't recommend continuing to use this module as we aren't actively developing it any longer.

SilverStripe Opauth Module

Uses the Opauth library for easy drop-in strategies for social login. See their documentation

Current Status

1.1 - stable. No known major issues. Report issues using the bug tracker.

How does it work?

The module provides an additional login form which the developer has control over, that allows users to instantly sign in to your website with an identity provided by any Oauth provider. The providers are each handled by using an OpauthStrategy, many of which are freely available. There are strategies for Facebook, Twitter, Google, and many more.

Based on the identity data from the Oauth provider, the module will find or create a new Member object based on the provided email address in the identity. This also means a Member can have many Oauth identities linked to a single account; these are saved in to the OpauthIdentity object.

If the resultant Member generated from the provider's response doesn't have an email address, or any other piece of data you require, there is functionality built in to handle this. You can enforce required fields, or any other kind of validation, by setting the OpauthValidator's custom_validator property to the class name of the validator you require.

Other than that, the user flow is quite simple. Provided all required data is there, the member is logged in with Member::login and then redirected to the page they were looking at or the default destination, settable in your config - just like the default MemberAuthenticator.


  • SilverStripe 3.1 (maybe 3.0, but untested so far)
  • At least one Opauth strategy
  • Preferably, allow_url_fopen enabled in php.ini. We've written a custom cURL workaround that works with Twitter, Google and Facebook strategies, but it's proprietary.
  • For extended cURL support we rely on an Opauth fork


What does this module include?

It includes:

  • the Opauth core (see below);
  • OpauthAuthenticator: intended to be comparable with MemberAuthenticator;
  • OpauthLoginForm: which offers different ways you can authenticate;
  • OpauthRegisterForm: which, if configured, provides an intermediate step so incomplete OpauthIdentity-authenticating members can fill in extra information as required;
  • OpauthController: which acts as a negotiator for the communication that strategies undertake;
  • OpauthIdentity: which acts as a service-agnostic interface with which to save Oauth identities in to the Member object. These are associated with a Member upon successful login so that the auth provider's UID and signed response act as a key.

NB: Opauth's maintainers recommend you include strategies as required, rather than bundling them together.

Where can I get strategies?

You can find a list under the "Available Strategies" heading on the Opauth homepage

Packagist provides a list of strategies you can use to install via Composer.

Where should I put strategies?

Use composer to require your strategies

How do I map the API responses to a Member?

You define the OpauthIdentity member_mapper block in your _config.yml. Simply provide a hash map of member fields to dot notated paths of the Opauth response array for simple fields, or if you need to perform some parsing to retrieve the value you want, an array of class name and function, like ['OpauthResponseHelper', 'get_first_name']. It takes the auth response array as an argument. See the example config YAML below for more details.

How do I configure the module and its strategies?

All Opauth-specific configuration variables can be put under opauth_settings and are passed directly to Opauth.

You can put these settings in your _config.yml file. Additionally, as your strategy API details will likely change per domain and thus per environment, you are able to update these using the Config API. Please see the Opauth config documentation. Here's some examples to help you:

_config.yml example:
Name: silverstripe-opauth
After: 'framework/*','cms/*'
# see the Opauth docs for the config settings -
    #Register your strategies here
    #Including any extra config
        app_id: ''
        app_secret: ''
        scope: email
        client_id: ''
        client_secret: ''
        key: ''
        secret: ''
    security_salt: 'correct horse battery staple'
    security_iteration: 500
    security_timeout: '2 minutes'
    callback_transport: 'session'
#Configuration for the Identity-Member mapping
      FirstName: 'info.first_name'
      Surname: 'info.last_name'
      Locale: 'raw.locale'
      Email: ''
      FirstName: ['OpauthResponseHelper', 'get_first_name']
      Surname: ['OpauthResponseHelper', 'get_last_name']
      Locale: ['OpauthResponseHelper', 'get_twitter_locale']
      FirstName: 'info.first_name'
      Surname: 'info.last_name'
      Email: ''
      Locale: ['OpauthResponseHelper', 'get_google_locale']
_config.php example:
//Register and configure strategies
Config::inst()->update('OpauthAuthenticator', 'opauth_settings', array(
  'Strategy' => array(
    'Facebook' => array(
      'app_id' => '',
      'app_secret' => '',
      'scope' => 'email',
    'Google' => array(
      'client_id' => '',
      'client_secret' => ''
    'Twitter' => array(
      'key' => '',
      'secret' => ''

//Identity to member mapping settings per strategy
Config::inst()->update('OpauthIdentity', 'member_mapper', array(
  'Facebook' => array(
    'FirstName' => 'info.first_name',
    'Surname' => 'info.last_name',
    'Locale' => 'raw.locale',
    'Email' => '',
  'Twitter' => array(
    'FirstName' => array('OpauthResponseHelper', 'get_first_name'),
    'Surname' => array('OpauthResponseHelper', 'get_last_name'),
    'Locale' => array('OpauthResponseHelper', 'get_twitter_locale'),
  'Google' => array(
    'FirstName' => 'info.first_name',
    'Surname' => 'info.last_name',
    'Email' => '',
    'Locale' => array('OpauthResponseHelper', 'get_google_locale'),

NB: As you can see, sometimes the Strategy configuration settings may have inconsistent namings - we can't help with that, sorry!
