Allows users to authenticate using their Google credentials

## Preparation

The following placeholders will be used:

-   `authentik.company` is the FQDN of the authentik install.

## Google

You will need to create a new project, and OAuth credentials in the Google Developer console. The developer console can be overwhelming at first.

1. Visit https://console.developers.google.com/ to create a new project
2. Create a New project.

_I'm only going to list the mandatory/important fields to complete._

11. **App Name:** Choose an Application
12. **User Support Email:** Must have a value
13. **Authorized Domains:** authentik.company
14. **Developer Contact Info:** Must have a value
15. Click **Save and Continue**
16. If you have special scopes configured for google, enter them on this screen. If not click **Save and Continue**
17. If you want to create Test Users enter them here, if not click **Save and Continue**
18. From the _Summary Page_ click on the \*_Credentials_ link on the left. Same link as step 8

25. Copy and store _Your Client ID_ and _Your Client Secret_ for later

## authentik

26. Under _Directory -> Federation & Social login_ Click **Create Google OAuth Source**

27. **Name**: Choose a name (For the example I use Google)
28. **Slug**: google (If you choose a different slug the URLs will need to be updated to reflect the change)
29. **Consumer Key:** Your Client ID from step 25
30. **Consumer Secret:** Your Client Secret from step 25

Here is an example of a complete authentik Google OAuth Source

Save, and you now have Google as a source.

## Username mapping

Since google does not have the concept of a username, authentik will by default prompt the user for a username when they first enroll through a google source. To change this behaviour and automatically use the email address as username, create an expression policy to set the username to the email, and bind it to the enrollment flow.

Create an expression policy with this expression:

```python
email = request.context["prompt_data"]["email"]
# Direct set username to email
request.context["prompt_data"]["username"] = email
# Set username to email without domain
# request.context["prompt_data"]["username"] = email.split("@")[0]
return False
```

Afterwards, edit the source's enrollment flow (by default _default-source-enrollment_), expand the policies bound to the first stage (_default-source-enrollment-prompt_), and bind the policy created above. Make sure the newly created policy comes before _default-source-enrollment-if-username_. Afterwards, any new logins will automatically have their google email address used as their username.

This can be combined with disallowing users from changing their usernames, see [Configuration](../../../docs/installation/configuration#authentik_default_user_change_username).
