Your account credentials have been saved in your Let's Encrypt
configuration directory at "/Users/**/go/src/github.com/go-acme/lego/.lego/accounts".

You should make a secure backup of this folder now. This
configuration directory will also contain certificates and
private keys obtained from Let's Encrypt so making regular
backups of this folder is ideal.
