Didn't even know it was a thing, thanks for sharing
Keep in mind face unlock on most devices is really not very secure. Apple is maybe the only one that comes close.
And for the people with internet, tv, radio or access to newspapers:
the police can make you look at the camera to unlock your phone (for example to check if you're aiding refugees from the ethnic lgbtq cleansing) but they cant (easily and in some countries legally) force you to type in a pin and password. I know the point is a bit moot for a pc as at that point the will just rip out your drive, assuming its not encrypted.
Still, worth mentioning imo.
As long as its more secure than no password where anyone can accidentally tinker on my device, thats my main concern with no pass
Windows Hello (and presumably modern Linux equivalents) use the camera + IR transmitters to work at least similarly to how apples Face ID works. In theory they should both be secure, but in practice who knows what they fucked up.
On howdy's own page it says that a well printed photo or someone who looks like you would be enough to fool it. Idk how secure Windows Hello is, but howdy is designed for convenience over security
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
