Plugin end of life starting from Moodle 3.3

starting from Moodle 3.3, Oauth2 should be implemented in Moodle core. It will require you to upgrade to Moodle 3.3 and switch to the Oauth2 core authentication (and probably do some migration), but it is a great news as authentication is a really sensible matter and having Oauth2 plugins in core will guarantee their maintenance. So starting from Moodle 3.3 I highly recommend to use the new Oauth2 core plugins ((https://docs.moodle.org/dev/Better_Office_Integrations_3.3#Core_API_for_managing_Authorized_OAuth_Applications) ) . Missing core providers will likely be implemented by someone and published in the Moodle.org plugin repository. There will probably be a new Oauth2 category in the Moodle plugin repository. Wait and see...

I will try to mantain this plugin until Moodle 3.1 (LTS) runs out of security upport  (13 May 2019).

Warning for Facebook users 

The plugin stopped working the 27th March 2017 as Facebook closed the API 2.2. The last versions of this plugin have been updated to support Facebook 2.8 API. As usual carefully test before upgrading a third party plugin if your Moodle site is important to you (especially as it is an authentication plugin)


  1. add the plugin into /auth/googleoauth2/
  2. in the Moodle administration, enable the plugin (Admin block > Plugins > Authentication)
  3. in the plugin admin page, follow the displayed instructions.

I also created a free mini-course on how to install a Moodle plugin using Oauth2 plugin as example.

    For an authentication plugin there's no standard strategy on uninstall itself, so it's very difficult to understand what you think an uninstall function should do.
    The changes to the db are quite simple, please send me a private message explaining what you want to do and i'll try to give you some instructions.

    Dear Brian,
    i'm Sergio and now i'm in charge for this plugin. I can confirm that there isn't a setting for email notification to admins about a new registration and there are no plans to add features to this plugin

    Buen día Sergio,
    Es probable el poder utilizar esta versión en un Moodle 3.6?

    Some users reported in the past that the plugin was usable, but i cannot and do not want to confirm this. Moodle 3.6 has it's own oauth2 client and i suggest to use that.

    Muchas gracias por el aporte, tengo unos usuarios pero no puedo ver su perfil, me dice que falta el auth_oidc, es factible solo instalarlo y no usarlo?

    Hello, is oauth2 plugin compatible with Moodle 3.5.2? Because i cannot find any plugin for authentication with Facebook in 3.5.2 version.

    Hi stavroula,
    If you're using moodle 3.5, just visit Site administration - Server - OAuth2 services and configure https://docs.moodle.org/35/en/OAuth_2_Facebook_service

    Since moodle 3.2 you should just configure your moodle from Site administration, as suggested by Phuong.
