Are there FLOSS-friendly versions of YubiKey?

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?
