    OpenSSH supports more than just simple passwords for authentication. It can be configured to use PAM (Pluggable authentication modules), Challenge/Response protocols, Kerberos authentication, authenticated host-based trust[1], and there are even patches for other methods, such as X509 keys. However the most popular alternate authentication method is Identity/Pubkey authentication. . . . OpenSSH supports more than just simple passwords for authentication. It can be configured to use PAM (Pluggable authentication modules), Challenge/Response protocols, Kerberos authentication, authenticated host-based trust[1], and there are even patches for other methods, such as X509 keys. However the most popular alternate authentication method is Identity/Pubkey authentication.

    The goal of using Identity/Pubkey authentication is to remove the need for static passwords. Instead of providing a password, which could be captured by a keystroke logger or witnessed as you type it, you have a key pair on your disk that you use to authenticate. Your account on the SSH server has a list of Identities/Pubkeys that it trusts, and if you can prove you have the public and private key then you are granted access without supplying a password.
