Setup WA OpenID

gistfile1.txt

To setup Work Adventure to authenticate with google oauth:

If you still don't have an Oauth Client:
- Access https://console.developers.google.com/ and create a project
- Setup the OAuth Consent Screen
- Go to credentials and create a new credential of type "Oauth Client ID"
- Under "Authorized Redirection URLs" make sure to fill with your Work Adventure full domain (https://play...)
- Save the configuration
- Next, you can either download the credentials or edit the credential. You will need the Cliend ID and the Client Secret

Now, you should have the required information to setup Work Adventure. You will need to set the following variables:

```
OPID_CLIENT_ID=<fill with the Client ID from previous step>
OPID_CLIENT_SECRET=<fill with the Client Secret from previous step>
OPID_CLIENT_ISSUER=https://accounts.google.com
OPID_CLIENT_REDIRECT_URL=
OPID_LOGIN_SCREEN_PROVIDER=https://<push domain>/login-screen
OPID_PROFILE_SCREEN_PROVIDER=
DISABLE_ANONYMOUS=true

OPID_SCOPE="openid email profile"
OPID_USERNAME_CLAIM="given_name"
OPID_LOCALE_CLAIM="locale"
```

OPID_USERNAME_CLAIM will specify which attributes from user profile will be used to name the user in the game. 
Other possible values are `name`, `last_name` and so on.

The variables that are unset are not required to make the authentication work.

Fill the following:

OPID_PROFILE_SCREEN_PROVIDER=https://www.googleapis.com/auth/userinfo.profile

It will become mandatory soon
