I am using honorlock for a lot of my classes currently. I am white so I can't speak to any problems to do with skin color but anecdotally I can say that it's awful to use lol. Even ignoring the obvious violation of privacy (we have to share our screen, record our face and in some cases do a full 360 degree "scan" of our room), it's super super buggy. I heard of someone who pressed tab and got their exam instantly ended because honorlock thought they were trying to cheat. I was doing a math exam and was looking down at my notebook, and the exam was paused because it couldn't detect any face. I also heard of a recent security breach they had and some people at my university got their information stolen. I didn't know that it was racist as well, but I'm not really surprised; the software barely works. So many people are complaining about it but none of the professors seem willing to budge. One of the more egregious examples I've seen of my University focusing less on teaching the material and more on making us jump through hoops for no fucking reason.
