SSH Linux login without password

Below is probably the quickest way to achieve this


1. Generate SSH key (if you don’t have one already)

ssh-keygen -t rsa


2. Use SSH to create a remote directory ~/.ssh

ssh mkdir -p .ssh


3. Append your public key to .ssh/authorized_keys on remote host

cat ~/.ssh/ | ssh 'cat >> .ssh/authorized_keys'



That’s it!
