Create own private & public key:

ssh-keygen -t rsa

(you can create a key without a password - especially for temp use)

Public key is here:

~/.ssh/id_rsa.pub

Public key needs to be put here into the target user of target server:

vi ~/.ssh/authorized_keys

Usage of new technique:

ssh user@server

ssh agent for private key in RAM

ssh-add

eval `ssh-agent`
