\"\"<\/p>\n

Want a Howdy alternative application for Windows Hello style facial authentication? Biopass is another one for your Linux Desktop.<\/p>\n

I’ve written about how to enable facial authentication using Howdy<\/a> in Ubuntu. The project however has not been updated for more than a year. And, the installation and setup are not friendly for beginners.<\/p>\n

<\/p>\n

There are a few Howdy alternative projects that were born with graphical user interface to make things simple for beginners. And, Biopass<\/a> is the one I’m going to introduce in this post.<\/p>\n

\"\"<\/a>

Biopass user interface<\/p><\/div>\n

Biopass is a free open-source application that supports using your face or fingerprint to authenticate<\/b> when you’re logging to your Linux system, launching applications or running something that requires user authentication.<\/p>\n

It uses AI models<\/i><\/b> to locate human face in camera captured image\/video and identify if it’s you by comparing the saved faces. It also supports using AI to determine whether a face in front of the camera is a real 3D human face or a fake presentation, such as photo, video replay, or mask.<\/p>\n

The app by default uses the open-source EdgeFace<\/a> model for face recognition, YOLO-Face<\/a> model for face detection, and minifas for anti-spoofing. While, user has the choose to use other ONNX AI models instead.<\/p>\n

\"\"<\/p>\n

It uses PAM<\/strong> (Pluggable Authentication Module) library to manage user authentication. It supports using either sequential<\/i> method that tries the supported authentication (facial and fingerprint) in order until one succeeds, or parallel<\/i> mode that can authentication in both ways at the same time while first success wins.<\/p>\n

And, it supports bypassing some PAM services, such as sudo<\/code> and pkexec<\/code>. In which cases, it won’t trigger your camera or fingerprint, instead using other authentication methods, such as password.<\/p>\n

\"\"<\/p>\n

Other features include graphical options for max retries and retry delay, IR camera anti-spoofing, multiple biometrics, and interactive polkit<\/code> authentication support.<\/p>\n

How to Install Biopass<\/h3>\n

Biopass provides official installer packages which are available to download in the Github releases page:<\/p>\n

\n
Download Biopass (under Assets)<\/a><\/div>\n<\/div>\n

Select amd64<\/code> or x86_64<\/code> for modern Intel\/AMD platform, arm64<\/code> or aarch64<\/code> for Snapdragon X or Raspberry Pi etc ARM64 devices, .deb<\/b> for Debian\/Ubuntu, or .rpm<\/b> for Fedora\/RHEL based distributions.<\/p>\n

Also download the AI models if you don’t have your own alternatives. For Ubuntu, the .deb<\/code> (v1.4.1) requires 26.04 and higher due to dependency library.<\/b><\/p>\n

\"\"<\/a><\/p>\n

After downloaded the installer, click open with your system package manager (e.g., App Center, GNOME Software) then install. <\/p>\n

Finally, search for and launch the application from your system app launcher or GNOME overview.<\/p>\n

\"\"<\/p>\n

When it opens, switch “AI models” tab to add your ONNX models, then switch back to “Configuration” tab to enable and configure facial authentication.<\/p>\n

After saved your configurations, open terminal (Ctrl+Alt+T) and run command sudo pam-auth-update<\/b> and enable Biopass authentication. Use Space<\/code> key to toggle on\/off selected PAM profile, and press Tab<\/code> key to switch to Ok button.<\/p>\n
