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? Also every time you type your password, you are sending your password over the network. So anyone who is eavesdropping on your connection will be able to intercept and crack your password. But if you switch to SSH keys you haven’t got anything to worry because your password is never transmitted over the network. Check out image below to get a vivid idea about the concept. So let’s get down to business(happy-face).
