Oauth2 authentication plugin for Moodle (for Moodle 3.2 and earlier)

Thanks William for helping James I will try to make some video demonstrating how to set it up.

Thank you for your help. Once i got rid of a trailing space the auth worked fine. That is great. I really appreciate your detailed help.

Once there...
1. Create Project > Give Project a name > Create
2. Select "APIs and Auth" > APIs > Select "Google+ API" > Enable Google+ API
3. Back to "APIs and Auth" > Credentials > Add Credentials > OAuth 2.0 Client ID >
4. However, it requires that you first configure the consent screen, so do that...most of it is optional...you can fancy it up if you like.
5. Select "Web Application", then give it a name, then paste the info from your Moodle Oauth2 settings page into the boxes and hit "Create".
6. That should be it.

James,
At the top of that Oatuth settings page in Moodle, there's a link to the Google Developer site you need to create the credentials. See here: http://www.awesomescreenshot.com/image/622020/406b83566e23605c1641210f5fd92829

Thanks William, do oauth2 and googleoauth2 work in conjunction with each other? The next question; is there a good way or tutorial for creating the client ID and secret using the google API?

James,
I apologize if this is obvious and not the problem, but there's a box on the Oauth2 settings page that needs to be checked to "Display buttons on login page"
Go to: Site Admin > Plugins > Authentication > Oauth2

Good luck,

Hi Jerome, simple question hopefully. I've installed the plugin, enabled under manage authentication and checked the settings to make sure they are valid including the mappings but I still cannot see the button. Is there another setting I am missing to show the button?

Hi Jonatan, this plugin won't help to authenticate in the Moodle mobile app - the mobile app currently authenticate by web service to Moodle - so except if Moodle became an authentication provider recently (and in this case we may be able to authenticate in Moodle through Google, then authenticate to the mobile app through Moodle) I don't think it is possible. Note that Moodle do provide some authentication through Mnet and other people already implemented Moodle as an authentication provider but I don't think any of that provide authentication to mobile apps.

Thanks for developing this valuable plugin.
but, Do I want to know if this works with moodle moblie application ?

Premezek: it seems very weird, I never heard of anything like the plugin been disabled automatically. Would you be able to do a screencast to demonstrate the problem? Then publish it on github. Thanks.

Just for the info I tested upgrade and it works. I installed a 2.5 site (plugin installed with Moodle.org plugin rep) then I upgrade the site straight to 2.9. Then through the Moodle admin I updated the Oauth2 plugin to the last plugin version (it is googleoauth2 2.1), it worked perfectly. My user that I used to login with Google was still able to login in.

I have problem with this plugin - when users starting to login thru Google accounts, the plugin disabling itself :/ Any ideas whats going wrong? It's a known problem?

I agree, Moodle admins should always test before installing/upgrading a critical plugin or a major Moodle install (for example have a duplicate of your production site on a different url).
About the issue, we don't know what was William's version.php file before the upgrade, so it is not easy to reproduce. I wrote this issue https://github.com/mouneyrac/moodle-auth_googleoauth2/issues/168 to make further investigation. Maybe it could also be a file permission issue as the Moodle.org upgrade process requires to change the auth folder permission. William, if you didn't delete the database table, but only the files, it may have been a permission problem in fact. Note: people can uninstall this plugin from Moodle (I think ). What there is not, is some specific uninstall code, and I can not remember if Moodle read the install.xml file during the uninstall process.
Also I would like to add that I appreciate if we could all keep support for this plugin on Github. Not here, and especially not by email, as it does not benefit others. Finally when I maintain this plugin or when I personally answer someone about this plugin, I give you my time. If you appreciate it you can "Favorite this plugin" on this page

Obviously, this is a helpful plugin, especially as schools (like ours) adopt Google Apps for Education, since this plugin allows easy sign-in into Moodle with student Google accounts and no need for additional usernames and passwords.
I ran into some trouble (see above) on 9/24/2015, when installing an update for this plugin. The update caused trouble and all of my users who had authenticated with this method (just over 500) could not sign into our LMS. We had to convert many of them to manual login (not fun) as we tried to figure out how to fix the problem. Mr. Mouneyrac was helpful in suggesting fixes after I contacted him by email. In the end, I just deleted the plugin folder from the server, installed the latest version of the plugin and it was fixed (there's no uninstall feature with this plugin, so I couldn't uninstall and re-install).
When running, this is a great plugin. If something goes bad...users can't sign in...and that can be a mess. So, install updates with caution.
