How to SSH without a password

What’s SSH & SSH Keys

SSH A.K.A Secure Shell is used to make remote connections between computers to execute commands. A username and password is used for the authentication purpose when establishing the connection. If you have a very strong password, it’s almost 100% secure to use SSH since the data transmission is encrypted. But are you comfortable with typing the lengthy password every time you want to SSH?
