Login with Facebook or Google+ account

Question

I want users to be able to log in (signup) in site with their Facebook or Google plus account. But I didn't find anything for Drupal 8.

Is there any module or solution for doing this job or I should downgrade and use Drupal 7 in our project?

Answer 1

This specific signup type is called OpenID. And it allows an external login provider to login users on your site.

You can have a look at OpenID Connect module. Which has a beta version for Drupal 8 available, and according to the module page already ships with a Google implementation.

OpenID Connect 1.0 is a simple identity layer on top of the OAuth 2.0 protocol. It allows Clients to verify the identity of the End-User based on the authentication performed by an Authorization Server, as well as to obtain basic profile information about the End-User in an interoperable and REST-like manner.

I am not sure about Facebook, but it might be that is in another contrib module or easy to implement yourself. (I didn't look for it.)

Answer 2

You can use module Simple OAuth. Some more details about it, from its project page:

... is an implementation of the OAuth 2.0 Authorization Framework: Bearer Token specification.

Using OAuth 2.0 Bearer Token is very easy. See how you can get the basics working in less than a minute!

This project is focused in simplicity of use and flexibility. When deciding which project to use, also consider other projects like OAuth, an OAuth 1 implementation that doesn't rely on you having https in your production server.
