SSH Allow Password For One User, Rest Only Allow Public Keys

Question

Is it possible with ssh to allow passwords from a certain user, but deny using passwords for everybody else?

Basically I want to allow password auth for user justin but everybody else must use public keys.

PasswordAuthentication no

Seems to be global though, no way to specify by user.

Answer 1

Necromancing, but adding the following to your sshd_config should do the trick:

Match User <username>
PasswordAuthentication yes
Match all

Note that match is effective "until either another Match line or the end of the file." (The indentation isn't significant.)
