Authorize keys ​

To login using a SSH key instead of a password, you must register the public key in the Windows you want to login into.

The path of the configuration file is different if your user have Administrative rights.

UserPath
Standard%USERPROFILE%\.ssh\authorized_keys
Admin%PROGRAMDATA%\ssh\administrators_authorized_keys
  1. Create the file if it already not exists;
  2. Append the public key into it;
  3. Admin only: Run the command bellow:
powershell
icacls.exe "C:\ProgramData\ssh\administrators_authorized_keys" /inheritance:r /grant "Administrators:F" /grant "SYSTEM:F"

Change default shell ​

powershell
New-ItemProperty -Path "HKLM:\SOFTWARE\OpenSSH" -Name DefaultShell -Value "PathToShell" -PropertyType String -Force
ShellPath
Git BashC:\Program Files\Git\bin\bash.exe
BashC:\WINDOWS\System32\bash.exe
WSLC:\Windows\System32\wsl.exe

Using Bash or WSL may give issues when using tools like sshfs.

WSL won't work when trying to run commands remotely (not interactive): ssh windows <command>.

For WSL, change the default shell with (run inside WSL2):

shell
sudo chsh -s $(which zsh)
