Setting up OpenSSH public key authentication
First upload your public key to the server you want to log in:
scp .ssh/id_rsa.pub user@1.2.3.4:/home/user
On the server, add the public key file to the authorized_keys file:
cat id_rsa.pub >> .ssh/authorized_keys
Now you can login using public key authentication and you don’t have to enter a password anymore.
