howdy
Star 3.4k Watch 57 Fork 204
Howdy provides Windows Hello™ style authentication for Linux. Use your built-in IR emitters and camera in combination with facial recognition to prove who you are.
Using the central authentication system (PAM), this works everywhere you would otherwise need your password: Login, lock screen, sudo, su, etc.
Installation
Howdy is currently available and packaged for Debian/Ubuntu, Arch Linux, Fedora and openSUSE. If you’re interested in packaging Howdy for your distro, don’t hesitate to open an issue.
Note: The build of dlib can hang on 100% for over a minute, give it time.
Ubuntu or Linux Mint
Run the installer by pasting (ctrl+shift+V) the following commands into the terminal one at a time:
sudo add-apt-repository ppa:boltgolt/howdy
sudo apt update
sudo apt install howdy
This will guide you through the installation.
Debian
Download the .deb file from the Releases page and install with gdebi.
Arch Linux
Maintainer wanted.
Install the howdy package from the AUR. For AUR installation instructions, take a look at this wiki page.
You will need to do some additional configuration steps. Please read the ArchWiki entry for more information.
Fedora
Maintainer: @luyatshimbalanga
The howdy package is available as a Fedora COPR repository, install it by simply executing the following commands in a terminal:
sudo dnf copr enable principis/howdy
sudo dnf --refresh install howdy
See the link to the COPR repository for detailed configuration steps.
openSUSE
Maintainer: @dmafanasyev
Go to the openSUSE wiki page for detailed installation instructions.
Setup
After installation, Howdy needs to learn what you look like so it can recognise you later. Run sudo howdy add to add a face model.
If nothing went wrong we should be able to run sudo by just showing your face. Open a new terminal and run sudo -i to see it in action. Please check this wiki page if you've experiencing problems or search for similar issues.
If you're curious you can run sudo howdy config to open the central config file and see the options Howdy has to offer. On most systems this will open the nano editor, where you have to press ctrl+x to save your changes.
CLI
The installer adds a howdy command to manage face models for the current user. Use howdy --help or man howdy to list the available options.
Usage:
howdy [-U user] [-y] command [argument]
| Command | Description |
|---|---|
add |
Add a new face model for an user |
clear |
Remove all face models for an user |
config |
Open the config file in your default editor |
disable |

list |
List all saved face models for an user |
remove |
Remove a specific model for an user |
snapshot |

test |
Test the camera and recognition methods |
version |
Print the current version number |
Contributing
The easiest ways to contribute to Howdy is by starring the repository and opening GitHub issues for features you'd like to see. If you want to do more, you can also buy me a coffee.
Code contributions are also very welcome. If you want to port Howdy to another distro, feel free to open an issue for that too.
Troubleshooting
Any python errors get logged directly into the console and should indicate what went wrong. If authentication still fails but no errors are printed you could take a look at the last lines in /var/log/auth.log to see if anything has been reported there.
If you encounter an error that hasn't been reported yet, don't be afraid to open a new issue.
A note on security
This package is in no way as secure as a password and will never be. Although it's harder to fool than normal face recognition, a person who looks similar to you or well-printed photo of you could be enough to do it. Howdy is a more quick and convenient way of logging in, not a more secure one.
To minimize the chance of this program being compromised, it's recommended to leave Howdy in /lib/security and to keep it read-only.
DO NOT USE HOWDY AS THE SOLE AUTHENTICATION METHOD FOR YOUR SYSTEM.
