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?
Yes they are - I own 3. Currently Nitrokey offers multiple different keys, but you most likely want to use the Nitrokey 3A.
