I am a private Linux user since many Years and I always have used combination of username and password to authenticate when logging via Secure Shell (SSH). It worked pretty well for Years but recently as my Linux footprint grew it started to be very tiresome. I knew that there is this “magical way” to login without password but I was reluctant to try it out. Once I tried it out I loved it and I never ever want to user password to authenticate with SSH. In this post you will learn how you can use combination of public and private keys to login to VMware ESXi.
