ich habe eben festgestellt, das mein SSH Schlüssel perfekt funktioniert und mich ohne Passwort Eingabe ins System lässt. Danach machte ich einen Test ohne geladenen Schlüssel und versucht nur per Passwort ins System zu kommen. Und das funktioniert zwar auch aber so wollte ich das sicherlich nicht. Ich habe mir dann mal die sshd_config angeschaut und diese scheint aber okay zu sein? Hier poste ich mal meine sshd_conf.

# 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.
#Port 22
#AddressFamily any
#ListenAddress 0.0.0.0

# This is the ssh client system-wide configuration file. See

# or on the command line.
# Configuration data is parsed as follows:
# 1. command line options
# 2. user-specific file
# 3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.
# Site-wide defaults for some commonly used options. For a comprehensive
# list of available options, their meanings and defaults, please see the
