use ssh-keygen command generate key in remote machine then

cd ~/.ssh

generate sshkey in remote machine , copy .pub file authorized keys , execute following command that

cat <key>.pub >> authorized_keys

copy other key file(private key) machine , using can login. use following command that

ssh -i <key-file> <username>@<ip>

if want implement ssh connection without of key file every time add generated .pub file in machine ~/.ssh/authorized_keys of remote machine can login giving ip or hostname
