using public key pairs is a much wiser thing to do than using passwords or lists of passwords. I will focus on things that are not widely known about different forms of SSH authentication, and I see no other answers mentioning them.

First of all, you must understand that user authentication is a different and separate process than the establishment of the secure channel. In laymans terms what this means is that first, the public key of the server is used (if accepted!) to construct the secure SSH channel, by enabling the negotiation of a symmetric key which will be used to protect the remaining session, enable channel confidentiality, integrity protection and server authentication.

So, to sum up, using public key pairs offers considerably more protection than using passwords or password lists which can be captured if the client, the server or the secure session is compromised. In the case of not using a passphrase (which shouldn’t happen), still public key pairs offer protection against compromised sessions and servers.

>Caution`

Do not share your private key with others.`
