I'm confused by this comment.

If you use ssh keys, does it matter whose accounts is compromised? Once
the account is compromised, couldn't they just load a keylogger?

And then, ssh keys still have passwords unless the creator of the keys
decides to omit a password.

Am I missing something here?

Well, the scenario I described actually happened years ago to someone I knew.
If I create keys without a passphrase, and share the public keys between
two systems (A and B), then from system A I can log to system B by
simply saying "ssh user@B". This is very convenient for cron jobs.

This is particularly risky when the systems are accessed by the general public.
How does someone finds out the username? I don't know... company phonebook,
online profiles listing first/lastname, etc.
