Fingerprint-enabled Passkey?

Context: My ThinkPad T490 has a fingerprint reader; I successfully configured it for sudo and login using PAM.

Now I want to  enable Passkey support for my Google/GitHub/Big Tech™ accounts, but they say my device doesn't support it. I consulted the Arch wiki and it told me to setup the FIDO2 Protocol for authentication using systemd-homed with homectl. I have the systemd-homed service enabled, so I can now use homectl. I looked up man homectl and the wiki page for homectl and it only mentions stuff about encrypting the home directory with LUKS; and mentions nothing of WebAuthn or Passkeys.

I'm completely lost — I have no idea how to configure passkey support and I don't wanna encrypt my /home or accidentally lock myself out.
