# pam_securetty.so is commented out since sshd already does a good job of
# protecting itself. You may uncomment it if you like, but then you may
# need to add additional consoles to /etc/securetty if you want to allow
# root logins on them, such as: ssh, pts/0, :0, etc

# When using pam_faillock, print a message to the user if the account is
# locked. This lets the user know what is going on, but it also potentially
# gives additional information to attackers:
#auth            requisite       pam_faillock.so preauth
auth            include         system-auth
# To set a limit on failed authentications, the pam_faillock module
# can be enabled. See pam_faillock(8) for more information.
