Answer 1

There are few steps need to be done to achieve this:

1. Log into machine X using ssh.
2. Trigger "ssh-keygen -t rsa". It generates key pair
3. Copy the generated public key .ssh/id_rsa.pub into another machine Y (the machine which you want to ssh without using password) at path .ssh/authorized_keys.
4. Do ssh Y . It will not ask password.
