These steps assume you already have a public SSH key, if not, create one

SSH-Copy-Id is an easier way to upload ssh keys, however, it does not work on all devices.

ssh to the remote server using your password.

If it is not already created, create the authorized_keys file under the .ssh folder

touch ~/.ssh/authorized_keys

chmod 600 ~/.ssh/authorized_keys

vi ~/.ssh/authorized_keys

Add your public key to the end of the authorized_keys file

Ensure that the correct owner and permissions are on the files.

The .ssh directory should be

chmod 700 .ssh

And the authorized_keys file should be 600

chmod 600 ~/.ssh/authorized_keys

Both should be owned by the user. Change username to your username.

sudo chown -R username:username .ssh/authorized_keys
