Quick start

Before starting, you should create an example app using the GOV.OK One Login admin tool.

1. Add "govuk_onelogin_django" to your INSTALLED_APPS setting like this:

   INSTALLED_APPS = [
       ...,
       "govuk_onelogin_django",
   ]
   

2. Include the govuk_onelogin_django URLconf in your project urls.py like this:

   path("one-login/", include("govuk_onelogin_django.urls")),
   

3. Include OneLoginBackend to your AUTHENTICATION_BACKENDS like this:

   AUTHENTICATION_BACKENDS.append("govuk_onelogin_django.backends.OneLoginBackend")
   

4. Include the following settings in your settings.py file

   # Required start page that includes a link to log in to GOV.UK One Login
   LOGIN_URL = "your-login-start-page"
   # A view name that the logged-in user will be redirected to after logging in via GOV.UK One Login
   LOGIN_REDIRECT_URL = "view-to-send-logged-in-users-to"
   
   # All other GOV.UK One Login settings required to configure govuk-onelogin-django
   GOV_UK_ONE_LOGIN_CLIENT_ID = "Your client ID"
   GOV_UK_ONE_LOGIN_CLIENT_SECRET = "Your client secret"
   GOV_UK_ONE_LOGIN_OPENID_CONFIG_URL = "Either integration or production config url."
   GOV_UK_ONE_LOGIN_SCOPE = "Required scopes"
   GOV_UK_ONE_LOGIN_AUTHENTICATION_LEVEL = "Required authentication level"
   GOV_UK_ONE_LOGIN_CONFIDENCE_LEVEL = "Required confidence level"
   

   Note: GOV_UK_ONE_LOGIN_CLIENT_SECRET is a base64 encoded string of your private key. e.g. base64 -i private_key.pem
