ACS AFD01-A1 Pocket Key High Speed ID Online FIDO® USB Security Key/FIDO U2F/FIDO2/FIDO2 CTAP2/2-Step Authentication

works great win 10, win 11, and linux mint. Great little modular bud, haven't had a problem with google, amazon, or microsoft websites. I do remove it when it's not in use, but hanging the cap would be optional if you want to keep it plugged in. light is rather bright. Best price, best value.Uses a pin or can use a pin. This is important if you're buying lots of cheap keys for family, some of the cheaper keys didn't support all functions like pin numbers. Has been reliable for weeks.

I like the compactness. I can verify it works on operating systems Windows7 and UP. The only reason i didn't give it 5 stars, i don't like that the light is ALWAYS on, and quite bright. I wish the light was off except for to blink when its expecting you to push the button.I ended up wrapping the outside with electrical tape. Two thinned strips. Top over to bottom, side over to other side. Like a crisscross. Now its black, and matches the laptop and i don't see that crazy bright light. It doesn't effect the pressing of the button.

I wanted to get 2FA for Discord (to mod a friend's server, who's a game dev, and who's game is getting popular now), but I didn't want to deal with the hassle that is using a cellphone.Plugged this baby in, and the entire process was pretty effortless. Discord detected it properly immediately, asked me to make a pin for it, and it just works.Minor gripe about an always-on very-bright blue LED on the USB key though. I'd give it 4.5 stars if I could, but 4 star rating instead, since there's no option for that.

It works. It's hard to find a small footprint security key. This one does everything I need, but damn the light is bright. Not sure why they put one on there. Maybe some people need it which is cool, but I wish there was a way to dim it.
