The SSH User Authentication dialog box enables users to select appropriate authentication methods. If a passphrase is not saved in a session, this dialog box is displayed in case it is necessary to obtain authentication-related information from the user.

Password
Password authentication is used to permit a user to log in to a server by entering the user account password. Due to security reasons, some servers do not support this authentication method.

Public Key
Public key authentication requires a user's public key to be registered in a remote SSH server. To log in using this method, select an appropriate user key from the user keys list.

Keyboard Interactive
Keyboard interactive acts as a server asking questions and the user replying with the correct messages.
