How to properly configure rsync for autodeploy?

Question

PHP

I use www.codeship.io to deploy the project
. I upload it via lftp. Deploy lasts 25 minutes, for a small project. Judging by logs there is a pass on all files.
I suspect there is a faster way with rsync. The documentation shows the following connection:
rsync -avz -e "ssh" ~/clone/ [email protected]:/path/on/server/
But what about the password, I suspect that you need to generate a public key, but how where??
From access there is ssh password and login.
