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)
- add the plugin into /auth/googleoauth2/
- in the Moodle administration, enable the plugin (Admin block > Plugins > Authentication)
- 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.
