Open SSH Authentication with Cygwin and Putty

Secure shell authentication (SSH Authentication) can be used by client to connect to a server remotely with encryption enabled. SSH or secure shell access offers a convenient way to access the servers terminal securely, however it becomes annoying if we need to type the password every time we need to connect to a server especially if we have a strong password in place. Doing it automatically offers a convenient and secure way to access our servers.

We can do this using OpenSSH if you have a Linux machine or Mac then by no means you already have it in your system. This article focus primarily in using OpenSSH via Windows machine, I just included the Cygwin to do this but it can also be done by using Putty alone.

So to start with, lets define what do we mean:

* Client: the system one types directly on, such as a laptop or desktop system.

* Server: anything connected to from the client.

Some precautions don’t allow your root account to do this, you can always run sudo command to perform administrative task. To do this of just add a user to the wheel group in Linux system to allow them to become
sudoers.
