Password Authentication

With passwords, it is also possible to use keyboard-interactive authentication. See Section Keyboard-Interactive Authentication for more information.

The password authentication method is the easiest to implement, as it is set up by default. Password authentication uses the /etc/passwd or /etc/shadow file on a UNIX system, depending on how the passwords are set up.

To enable password authentication, make sure that the AllowedAuthentications field of the /etc/ssh2/sshd2_config and /etc/ssh2/ssh2_config configuration files contain the parameter password:

        AllowedAuthentications   password

Other authentication methods can be listed in the configuration files as well.
