Configure Google login for Discourse

[Discourse]

Steps

1. Go to https://console.developers.google.com, on the top left click on Select a project
   

   

2. On the top right, click on New Project
   

   

3. 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.)
   

   

   3a. It is possible that errors are displayed after creating the project. Ignore them and refresh the page with Ctrl+F5
   

   

4. Select your project by clicking on the project name, click on OAuth consent screen on the left panel (if you can’t find it, search using the search box at the top), select External and then click on Create

   

5. Fill as appropriate; we recommend populating all these fields, then click Save.
   In the example below we use https://demo.site.com, be sure to use the URL of your Discourse site including http:// or https://. All our hosted customers have HTTPS active by default.

   As of 2021/09/13 (September 13), Google will require you to use https.

   Noting that changing the Application logo, Google will ask to verify the site

6. Go to the Credentials tab on the left, click on + CREATE CREDENTIALS and then click on OAuth client ID
   

   

7. Choose Web application as the Application Type.
   In the Authorized JavaScript Origins section, add your site’s base url, including http:// or https://.
   In the Authorized Redirect URI section, add the base url with /auth/google_oauth2/callback. Click the Create button.

   As of 2021/09/13 (September 13), Google will require you to use https.

   

8. The OAuth client dialog will appear with client ID and secret.
   

9. (Optional) From your project, clicking on Credentials from now on you will find the OAuth credentials to edit or delete

10. In your Discourse site settings, check enable google oauth2 logins, and fill in your google oauth2 client id and google auth2 client secret provided earlier.

11. Your ‘project’ will have the ‘Testing’ status. Add a google user, and test that it is working.

12. To get it fully working, you now have to change the status to In production. This means filling in a few more things, and submitting it for verification. For details see, OAuth App Verification Help Center - Google Cloud Platform Console Help
    

    

13. You will need to confirm your ownership of the site via the Google Search Console to make Google happy. See this:

Perform Google Search Console (a.k.a Google Webmaster Tools) Verification with Discourse

This howto goes over the methods you can use to verify domain ownership for Google Search Console, while using Discourse. There are two methods you you can use to do this verification: Create a TXT DNS record - this is your best option! Add HTML Tag - only use this method if you don’t have DNS access, or can’t get a TXT DNS record to work. Both methods start out the same: In the Google Search Console (GSC) https://search.google.com/u/1/search-console set up a new property by entering the U…

That’s it, Google login should now work on your Discourse! Go ahead and test it out with any Google account.
