If the identifier is not in your known_hosts file (which is the case the first time you connect to them), you are asked if you accept that identifier, and if so, it is added to your local ~/.ssh/known_hosts. This identifier is sent to your system during the login process.

As an added protection (mostly useful when you use a password login AFAIK), the systems you connect to have an identifier.

This is done either manually with an editor or using the ssh-copy-id utility. On these other systems, the userids that you can login to have your public key added to their ~/.ssh/authorized_keys file, which, as its name implies, collects the public keys of all the people that can log in as that userid.

During the login process, SSH uses you local private key to do something that can be checked on the other system using your public key.This requires a pair of keys that you generate, one private ( ~/.ssh/id_rsa) and one public ( ~/.ssh/id_rsa.pub).SSH without passwords works with "assymetric keys".A quick summary of how SSH works and the purpose of the various files. Nothing to do, except remove the keys you created ( ~/.ssh/id_rsa and ~/.ssh/id_rsa.pub).
