You can disable password login by editing /etc/ssh/sshd_config like this:

File: /etc/ssh/sshd_config
...
ChallengeResponseAuthentication no
PasswordAuthentication no
UsePAM no

Before running the following command, make sure you have configured ssh keys properly and can login with them. Otherwise you won't be able to login remotely.

# you may need to run a different command based on your system
sudo systemctl restart ssh.service
