There are two commands adduser and useradd. According to the manpage
(man useradd) it is more convenient to use adduser.

As it comes to keys see below how I usually do it - on debian though
***** Create Key
me@client:~$ ssh-keygen -t rsa -b 4096 -C "mykey"
me@client:~$ ls -l ~/.ssh | grep mykey*
-r-------- 1 me me 3326 Dec 31 12:46 mykey
-r-------- 1 me me 744 Dec 31 12:46 mykey.pub
***** Deploy Key
me@client:~$ ssh USER@HOST "echo \"$(cat ~/.ssh/public-key.pub)\" >>
.ssh/authorized_keys"
me@host:~$ ls -la | grep ssh
drwxr-xr-x 2 me me 4096 Dec 31 11:53 .ssh
me@host:~$ ls -l .ssh/authorized_keys
-rw------- 1 me me 744 Dec 31 11:55 .ssh/authorized_keys
***** Edit /etc/ssh/sshd_config on Host
Change
PasswordAuthentication yes
into
PasswordAuthentication no
Then do 'systemctl restart ssh.service'
