Howdy

Howdy is a program that imitates Windows Hello on Linux. It uses a computer's IR sensors and camera to verify a user's face.

Installation

Install the howdyAUR package.

Configuration

Setup Howdy to start when needed

In order for Howdy to authenticate a user, a small change must be added to any PAM configuration file where Howdy might want to be used. The following line must be added to any configuration file:

auth sufficient pam_python.so /lib/security/howdy/pam.py

Example

/etc/pam.d/sudo
# PAM-1.0
auth    sufficient pam_python.so /lib/security/howdy/pam.py
auth    include    system-auth
account include    system-auth
session include    system-auth

Add correct IR sensor

Determine the correct /dev/videoX file connected to the IR sensor. This can be done through various programs such as cheese and fswebcamAUR. Once the correct filename is found, edit /lib/security/howdy/config.ini using either your preferred editor or with sudo howdy config.

Note: gedit must be installed for sudo howdy config to work.

Add face to Howdy

In order to add a face model to Howdy, run sudo howdy add.

Troubleshooting

Howdy doesn't seem to work

Verify that Howdy is properly working by running howdy test as root. If that seems to work, check any PAM configuration files and verify they are working. Some programs, such as SDDM [1], do not work properly with PAM, which may result in unexpected results.
