Passwords may be accepted by both the PasswordAuthentication and KbdInteractiveAuthentication authentication schemes. Add a reference to the latter in the description/comment for PasswordAuthentication, as it otherwise may seem that "PasswordAuthentication no" implies passwords will be disallowed. This situation should be clarified with more extensive documentation on the authentication schemes and configuration options, but that should be done in coordination with upstream OpenSSH. This is a minimal change that will hopefully clarify the situation without requiring an extensive local patch set.

# $OpenBSD: sshd_config,v 1.104 2021/07/02 05:11:21 dtucker Exp $

# This is the sshd server system-wide configuration file. See
|
|
# sshd_config(5) for more information.
|
|
|
|
# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin
|
|
|
|
# The strategy used for options in the default sshd_config shipped with
|
|
# OpenSSH is to specify options with their default value where
|
|
# possible, but leave them commented. Uncommented options override the
|
|
# default value.
|
|
|
|
# Note that some of FreeBSD's defaults differ from OpenBSD's, and
|
|
# FreeBSD has a few additional options.
