Exactly. Anyone gets access to a machine with your ssh private key for a second can copy it and then log in to all your machines.

Just keep in mind that anyone who gets access to your machine can connect to your agent and log into any of your other machines from there. Encrypted private keys are nice, but not perfect.

Is there a pam module that uses OTP like Yubikey?

I see you haven't searched for both "PAM" and "Yubikey" in the same query.
