Windows 10 has since some while ago a OpenSSH client included. There is also an option to install a OpenSSH server. One issue I regularly encounter is that the server is as default setup to not allow my user to login using the authorized_keys file located at %USERPROFILE%\.ssh\ as my user is a local administrator. Let’s fix this.

Installing OpenSSH Server

This is most conveniently done using Windows Settings.

1. Open Windows Settings (WIN+I)
2. Navigate to Apps
3. Select Apps & Features
4. Open Optional features
5. Select Add a feature
6. Scroll down to OpenSSH Server
7. Press Install

Enabling SSH login

1. Open a notepad or your favorate text editor as administrator.
2. Open sshd_config located at: C:\ProgramData\ssh\sshd_config
3. Find the following line: Match Group administrators, for me this is in the bottom of the file.

4. Comment the following 2 rows:

   Match Group administrators
       AuthorizedKeysFile __PROGRAMDATA__/ssh/administrators_authorized_keys
   

5. Restart service OpenSSH SSH Server
