hello guy
I setup a ssh server. everything is ok. I have a question:
How can i allow users to login ssh server only using the key? nor user's password. Just
deny password login in ssh.
Thanks a lot.

Have a look at /etc/ssh/sshd_config

Change
PasswordAuthentication yes to no

Then exchange public keys and append then to .ssh/authorized_keys

cat host.pub >> authorized_keys

Then you can use a blank passphrase (which is bad)
or use a passphrase once if using the key agent in the background.

You can then login without password Authentication. It uses the keys instead

thank you neil
yes, my PasswordAuthentication is set to no, i can login using passphrase normally, but if i don't using passphrase(skip), i can use user password to login ssh too, I want to deny the user password to login ssh. how can i do?
