I rarely use my smartphone and find it a bit annoying to have to use it for 2FA through apps. I wish to get physical passkeys that will allow me to login to my laptop.
I have heard of YubiKey although I haven’t given it any serious consideration since it is closed source. (My super-tin-foiled friend who introduced me to this world of privacy taught me to never trust a closed-source solution… _long _ story).
Are there any FLOSS versions of Yubikey? Can they be used to log into a Linux machine? Or for banking?
I believe solokeys are open source. I use a solo v1 for sudo, ssh, and two factor websites. They either went out of business or are basically defunct as I understand it, but you can pick them up on crowd supply. I wouldn’t get the v2, supposedly they had problems and that’s why they shut down. You likely won’t see updates, but they do function for what you’re looking for. There are some that are shaped like a small thumb drive and some that sit almost flush with a USB port. Some have nfc, which is useful for phones. Buy at least 2 though, and register both for everything, because you don’t want to lock yourself out of something.
I use Solokeys. Didn’t know they were defunct. I just bought another from then a month or so ago. I use it for MFA, ssh, and sudo, and I’m trying to config Kubuntu login screen to require solokey but no luck yet.
I like solokeys, but the one I recently bought has NFC and, technically, my pixel7 running GraphenreOS can detect the device, but it doesn’t work. Many people reported this issue. In my experience, NFC is non-functional.
I’m pretty sure you have to have google play services or MicroG for FIDO2 to work on android. A bit silly of you ask me.
