This is a _very quick_ tutorial on how to configure Google authentication in your application using the default oauth2 strategy in ash.
First you'll need a registered application in [Google Cloud](https://console.cloud.google.com/welcome), in order to get your OAuth 2.0 Client credentials.
1. On the Cloud's console **Quick access** section select **APIs & Services**, then **Credentials**
2. Click on **+ CREATE CREDENTIALS** and from the dropdown select **OAuth client ID**
3. From the google developers console, we will need: `client_id`&`client_secret`
Next we configure our resource to use google credentials:
Please check the guide on how to properly configure your Secrets
Then we need to define an action that will handle the oauth2 flow, for the google case it is `:register_with_google` it will handle both cases for our resource, user registration & login.
``` elixir
defmodule MyApp.Accounts.User do
use Ash.Resource, extensions: [AshAuthentication]
# ...
actions do
create :register_with_google do
argument :user_info, :map, allow_nil?: false
argument :oauth_tokens, :map, allow_nil?: false
upsert? true
upsert_identity :email
change AshAuthentication.GenerateTokenChange
# Required if you have the `identity_resource` configuration enabled.
