Having SSH and SFTP with my New Web Hosting meant a little more configuration to be able to login without a password prompt every time. A2 had a good writeup on creating SSH keys - just be sure to put the public one on the server.
Where I got mired was using the keys on the command line, which wasn’t always well documented. Here’s SSH:
ssh -pport user@hostname.com'
And LFTP:
lftp -p port -u user,placeholder sftp://hostname.com
Both assume you put your SSH keys in the default ~/.ssh directory and that your host uses a non-standard SSH port. The placeholder for LFTP is just that - some text is needed after the comma to stop it from prompting for a password.
