He intentado un par de formas de hacerlo y la primera que funcionó para mí fue ssh-copy-id
#By default this puts keyfile pair in ~/.ssh/id_rsa & ~/.ssh/id_rsa.pub :
ssh-keygen.exe -t rsa -b 2048
ssh-copy-id -i ~/.ssh/id_rsa.pub $remoteuser@$remotehost
# I'm not sure if these two chmod lines are needed on windows but
# typically ssh refuses to use a private key file
# if it is less-well protected than this:
chmod 700 ~/.ssh
chmod 640 ~/.ssh/id_rsa
La forma más fácil de obtener las ssh
herramientas es instalar git para Windows.
Ejecuté los comandos anteriores desde el shell bash instalado por git. Ejecutar ssh-copy-id de powershell de alguna manera no funcionó, así que terminé con este script de PowerShell
