Connecting with PuTTY to Amazon EC2 Windows instance running freeSSHd

Question

I could connect to EC2 Linux instance using PuTTY, but I need to connect it to Amazon EC2 Windows instance.

I installed freeSSHd server on EC2 Windows instance to support SSH client request on port 22. SSH server is running on port 22.

When I tried to connect, it is asking for a password. After trying with some of the available passwords, it is rejecting the connection. I have tried with usernames ec2-user, root & administrator.

The link that gone through for the putty configuration: "Server Refused our key" after launching instance from private EBS AMI
Connect ssh(putty) to ec2 instance

Is it possible to connect to the Amazon EC2 windows instance using PuTTY?

There's no SSH server in Windows by default. Though, if you are getting prompted for password, you must have installed SSH server. Did you? — Martin Prikryl

First, freeSSHd is unreliable and obsolete server. I suggest you use a different one.

Actually, Microsoft now provides a beta version of OpenSSH port for Windows.

Anyway, configure the accounts in freeSSHd settings. And then use the configured credentials in PuTTY.
