SSH keys
SSH keys are a secure method of passwordless SSH authentication.
You can create a keypair using various algorithms, ed2559 is currently considered the most secure.Generate SSH keys
ssh-keygen -t ed25519 chmod 600 ~/.ssh/*Authorize SSH keys
Append your public key to a new line in
~/.ssh/authorized_keys
to allow SSHing ing as that user on that server.SSH is picky about permissions.
mkdir ~/.ssh chmod 700 ~/.ssh touch ~/.ssh/authorized_keys chmod 600 ~/.ssh/authorized_keys cat id_ed25519 >> ~/.ssh/authorized_keysPermissions
On windows, permissions are tricky.
icacls .\private.key /inheritance:r icacls .\private.key /grant:r "%username%":"(R)" # if you've broken permissions, reset using gsudo icacls .\private.key /T /Q /C /RESET
