1.Use ssh-key instead of password

• Add a new user on server. (e.g. bird)

adduser bird
passwd bird
usermod -aG wheel bird  #add user to sudo group

• Generate ssh-key at local computer

ssh-keygen

• Copy your local public key to server

ssh-copy-id $user@Your_server_ip -p[port]

• Change authority of file or dirctory

chmod 600 /home/bird  # Some OS do not need this step ?
chmod 700 /home/bird/.ssh
chmod 600 /home/bird/.ssh/authorized_keys

• At server terminal type:

vi /etc/ssh/sshd_config

• So change sshd_config file as follow:

RSAAuthentication yes
PubkeyAuthentication yes
# set your ssh key position
AuthorizedKeysFile  /home/bird/.ssh/authorized_keys 
PasswordAuthentication no
ChallengeResponseAuthentication no
PermitRootLogin without-password

• Then reload sshd

systemctl restart sshd
systemctl reload sshd

• Now test your ssh key pair. It is success if login without password prompt.

ssh bird@123.123.123.123 -p [port]

If something wrong happened, use "ssh -v bird@your_server_ip" to debug.
