That is one of the reasons why you should use a smartcard based key - at least for the root account. You can't brute force that (as long as you use a non obvious PIN).

Now you may only mount an active attack by taking over an already authenticated connection using a modified ssh client. However, it is mood to speculate over such scenarios because there is no way you can protect yourself from a taken over machine.

except that OpenSSH has a bug open since _years_ to enable "ask for PIN" functionnalilty, without it it's useless...

Well, I never used that.

GnuPG implements the gpg-agent protocol since 2005 and ever since allows the use of smartcards - including PIN entry. It even utilizes the PINpad on some readers.
