Omitting Password Prompt for SSH

On the Linux Bash language command line/console, I’ll introduce how to omit the password prompt for SSH connections.

ssh-keygen -t rsa # if you don't have yet.
ssh user@domain.com mkdir -p ~/.ssh
cat ~/.ssh/id_rsa.pub | ssh user@domain.com 'cat >> ~/.ssh/authorized_keys' # I like this way of writing
ssh user@domain.com # you've being able to bypass password
# This means adding the client's public key to the server.

The ConoHa VPS password is 9 digits, but after typing it about 50 times, it became troublesome.
