The following instructions are based on my HowTo: SSH key with PuTTY and PuTTYgen, which already described password-free SSH public key authentication from a local Linux system to a remote Linux server. **By integrating the **private key already generated with PuTTYgen into the Windows program WinSCP, **password-free access to a remote Linux server can also be achieved here.
WinSCP can be downloaded as a Windows installer from the WinSCP download page.
-
Launch WinSCP from the Windows programs list.
-
In the Session / Transfer Protocol section on the left, select SCP from the drop down menu.
-
In the Session/Host name and Port number sections, enter the IP address of the remote server you wish to connect to and, if necessary, adjust the port to be used. In this example, the IP address 172.16.1.12 and port 22 are used.
-
In the Session / User name section, enter the user name with which you wish to log on to the remote server. In this example the superuser root is used.
-
Click on the Advanced button
-
Select SSH / Authentication in the right pane and then click on the yellow marked button in the right pane Authentication parameters / Private key file: to search the file system for the private key that you have already created according to my instructions HowTo: SSH-Key with PuTTY and PuTTYgen and saved in a safe place.
-
Select the appropriate file and click Open.
-
The path including the filename should now be displayed in the yellow highlighted text box. Click the OK button to return to the WinSCP login page.
-
Save your entries by clicking the *Save button.

Enter any name in Site name: or use the default name. Click OK to save the session.
