NAME¶pam_securetty - Limit root login to special devices
DESCRIPTION¶pam_securetty is a PAM module that allows root logins only if the user is logging in on a "secure" tty, as defined by the listing in /etc/securetty. pam_securetty also checks to make sure that /etc/securetty is a plain file and not world writable. It will also allow root logins on the tty specified with console= switch on the kernel command line and on ttys from the /sys/class/tty/console/active.
This module has no effect on non-root users and requires that the application fills in the PAM_TTY item correctly.
For canonical usage, should be listed as a required authentication method before any sufficient authentication methods.
