It’s enjoyable to setup face unlock on Linux. I believe this might present base for some good Raspberry Pi tasks. It’s a enjoyable weekend train to do a factor like this.

Nonetheless, I gained’t advocate establishing it on vital infrastructure or servers. Facial recognition isn’t very safe.

Utilizing face unlock in your private Linux system is one factor however please don’t apply it to servers or work machines.

I hope you appreciated this DIY (if I’ll name it) tutorial. Let me know if you need to see extra such tutorials on It’s FOSS sooner or later.
