Login with FB, google and apple only

[kforr (Kel)]

Hi all,
I’m new to Discourse
I’ve just setup the discourse on azure now.
Working on the login, I’d like the forum to only login using Facebook account or Google account or Apple ID. (I don’t want to allow people register with email address)

1st question is if this is possible?
I’ve looked a few posts here and got myself confused… sorry

This post is how to configure facebook login:

Configure Facebook login for Discourse

As of February 2023, Meta has implemented a business verification requirement when publishing new and existing apps. Updating the Facebook app API or creating a new app will break existing logins. See troubleshooting at the bottom of this post for a solution. Configuration Go to developers.facebook.com/apps and … Login with the credentials of the account you want to connect to Discourse and follow the wizard. If you already have other apps instead of Get Starte…

This post is how to configure google login:

Steps Go to https://console.developers.google.com, on the top left click on Select a project [image] On the top right, click on New Project [image] Fill in the Project Name field. You can also edit the Project ID (optional), then click on Create (This can take a while, so wait a minute as needed for it to appear.) [image] 3a. It is possible that errors are displayed after creating the project. Ignore them and refresh the page with Ctrl+F5 [image] Select your project by clic…

And this post from Sam is for all the OAuth and it’s the official way:
Oops I can only put 2 links, this is the official: DiscourseConnect - Official Single-Sign-On for Discourse (sso)

2nd question is: if I only want facebook, google and apple ID, which one should I follow?

3rd question is: if I want to open up registration using email address in the future, is it ok? and what should I do?

Last question is: (this might be a different topic) I’d like my site and Discourse to share same login (I haven’t built my site yet but it will be in ASP .NET C#) my site will only allow the same FB,google and apple probably email in the future. How can Discourse read my database?

Thanks heaps for the help!!

1st question is if this is possible?

Yep, you need to disable the enable local logins site setting

@kforr

2nd question is: if I only want facebook, google and apple ID, which one should I follow?

You should follow the Facebook, Google and Apple instructions

@kforr

3rd question is: if I want to open up registration using email address in the future, is it ok? and what should I do?

Yes, you can just turn enable local logins back on

@kforr

How can Discourse read my database?

If you want authentication to happen on your own site, you need to choose a protocol to use. The most common is OAuth2 or OpenID Connect. You could also use Setup DiscourseConnect - Official Single-Sign-On for Discourse (sso). This will all require significant development work on your app to get things working.

Thank you very much David.
Can I please confirm this following of what I will be building if that’s correct as I’m new to OAuth2:

Because the website will be the entry point so I will implement OAuth2 on my website with Google/FB/Apple only. When user clicks on the ‘Forum’ on my site, it will redirect to Discourse, so on Discourse I just need to choose to use OAuth2 protocol? so users are already logged in when they come to Discourse forum?

Last question, I have hosted Discourse in Azure, if I host my website in AWS or in another Azure account, would it be ok? (they will be on the same domain, Discourse will be a subdomain e.g. forum.example.com

Thank you very much!!

If your website is handling the Facebook/Google/Apple auth, then yeah the link to Discourse could be just OAuth2

@kforr

host my website in AWS or in another Azure account

Yeah that’s fine, it shouldn’t matter where the different components are hosted

Got it, thanks again David!!
