Kagi provides support for FIDO WebAuthn security keys and TOTP tokens in Django.



Kagi is a relatively young project and has not yet been fully battle-tested.

Its use in a high-impact environment should be accompanied by a thorough

understanding of how it works before relying on it.



`Full documentation is hosted on Read the Docs`_. 



Installation

------------



::



    python -m pip install kagi



Add ``kagi`` to ``INSTALLED_APPS`` and include ``kagi.urls`` somewhere in your

URL patterns. Set: ``LOGIN_URL = "kagi:login"``



Make sure that Django’s built-in login view does not have a

``urlpattern``, because it will authenticate users without their second

factor. Kagi provides its own login view to handle that.



Demo

----



To see a demo, use the test project included in this repository and perform the

following steps (creating and activating a virtual environment first is optional).



First, install Poetry_::



    curl -sSL https://install.python-poetry.org/ | python -



Clone the Kagi source code and switch to its directory::



    git clone https://github.com/justinmayer/kagi.git && cd kagi



Install dependencies, run database migrations, create a user, and serve the demo::



    poetry install

    poetry shell

    invoke migrate

    python testproj/manage.py createsuperuser

    invoke serve



You should now be able to see the demo project login page in your browser at:

http://localhost:8000/kagi/login



Supported browsers and versions can be found here: https://caniuse.com/webauthn

For domains other than ``localhost``, WebAuthn requires that the site is served

over a secure (HTTPS) connection.



Since you haven’t added any security keys yet, you will be logged in with just a

username and password. Once logged in and on the multi-factor settings page,

choose “Manage WebAuthn keys” and then “Add another key” and follow the provided

instructions. Once WebAuthn and/or TOTP has been successfully configured, your

account will be protected by multi-factor authentication, and when you log in

the next time, your WebAuthn key or TOTP token will be required.



You can manage the keys attached to your account on the key management page at:

http://localhost:8000/kagi/keys



Using WebAuthn Keys on Linux

============================



Some distros don’t come with udev rules to make USB HID /dev/

nodes accessible to normal users. If your key doesn’t light up

and start flashing when you expect it to, this might be what is

happening. See https://github.com/Yubico/libu2f-host/issues/2 and

https://github.com/Yubico/libu2f-host/blob/master/70-u2f.rules for some

discussion of the rule to make it accessible. If you just want a quick

temporary fix, you can run ``sudo chmod 666 /dev/hidraw*`` every time

after you plug in your key (the files disappear after unplugging).



Gratitude

=========



This project would not exist without the significant contributions made by

`Rémy HUBSCHER `_.



Thanks to Gavin Wahl for `django-u2f `_,

which served as useful initial scaffolding for this project.
