SSH – How to Disable Password Access Through SSH

passwordremote accessSecurityssh

I'm setting up a server for backing up my desktop box remotely. I want to prevent remote password access to the server, permitting only users with private keys (AKA my desktop box) to access it. How can I block remote password access while allowing physical password access to the server?

Best Answer

Just insert the following to the sshd config on the server (/etc/ssh/sshd_config)

PasswordAuthentication no

You might need to reload the ssh service

sudo service ssh reload

That should do the trick ;)

For more options type man sshd_config in to your terminal.
