SSH keys are a way to identify computers, without using passwords. If you have used git, or if you are an active participant in the open-source community, you will be definitely familiar with the important role of SSH.

And by making configuration changes it also allows the user to provide more security to server/system that we are using. Some of the main features are listed below.
