How to automate SSH Login with PuTTY

generate the key pairs with PuTTYgen (puttygen.exe)
Save Private Key and save it somewhere on your computer.
On the server, create the file ~/.ssh/authorized_keys containing the generated public
key on a single line.
Make this file readable (chmod 600).
open up PuTTY and navigate to Connection->Data and fill in the
auto-login username.
Connection->SSH->Auth and under Private-key, browse to the file you had
saved earlier on your computer.

If message “Server refused our key” is generated, remember that permissions for .ssh or authorized_keys should exactly follow grants issued with “chmod 700″ for .ssh and “chmod 600″ for authorized_keys. (chmod 700 .ssh is not necessary but it is recommended.)
