I'm using Atom editor with SCP/SFTP remote-sync plugin to edit remote files (on mac). I'm trying to config the plugin without giving it plain password. What's the path to ssh key on a mac? And what's a Passphrase for the SSH key (only used for SCP)? Thanks.
Your SSH keys are located in ~/.ssh.
We don't know your local key passphrase on your Mac. If you're generating a new key and don't want to deal with a passphrase then just hit enter when prompted to enter a new passphrase.
