Dependencies

• Python 3.5 and higher
• Django >= 1.11

Configuration

1. Add django_fido to INSTALLED_APPS.

2. Add django_fido.backends.Fido2AuthenticationBackend to AUTHENTICATION_BACKENDS.

3. Link django-fido URLs into your urls.py:

   urlpatterns += [
      url(r'', include('django_fido.urls')),
   ]
   

4. If you wish, set string variable DJANGO_FIDO_RP_NAME.

One step authentication

You can also decide to use one step authentication. In this case, you will use just one authentication form, that will collect username, password and FIDO2 credentials. In addition to the configuration above, you also need to:

1. Set DJANGO_FIDO_TWO_STEP_AUTH to False.
2. Replace django_fido.backends.Fido2AuthenticationBackend with django_fido.backends.Fido2GeneralAuthenticationBackend in AUTHENTICATION_BACKENDS.
3. Set DJANGO_FIDO_AUTHENTICATION_BACKENDS to the list of your additional authentication backends, if you use others than django.contrib.auth.backends.ModelBackend.
4. Set data-autosubmit-off attribute on the form element of your login page.

Please note that your login form must have a field named username, even if your USERNAME_FIELD is not username.

Metadata download

If you want to be able to download authenticator metadata, you need to set DJANGO_FIDO_METADATA_SERVICE setting. It is a dictionary, with an ACCESS_TOKEN as the only mandatory key. Then you can periodically run the download_authenticator_metadata management command. If metadata are available for the given Authenticator, its metadata property will be an object. The level, vulnerabilities and is_update_available methods on metadata can be used to determine the trust and certification level.
