Using key-based SSH logins, you can disable the normal username/password login procedure which means that only people with a valid private/public key pair can log in. That way, there is no way for brute-force attacks to be successful, so your system is more secure. Also, public key authentication is simple and secure solution for remote password-less connections between servers.Create a pair of ssh authentication keys, private and public: ssh-keygen -t rsa -b 4096.

One immediate advantage this method has over traditional password authentication is that you can be authenticated by the server without ever having to send Login with putty. In the above exmaples we used the openssh ssh client that is available on linux.However putty cannot use the private key generated by the ssh-keygen command directly. It uses its own format.
