SECURETTY(5)                        Linux Programmer's Manual                        SECURETTY(5)

NAME
       securetty - file which lists terminals from which root can log in

DESCRIPTION
       The  file  /etc/securetty  contains  the names of terminals (one per line, without leading
       /dev/) which are considered secure for the transmission of certain authentication tokens.

       It is used by (some versions of) login(1) to restrict  the  terminals  on  which  root  is
       allowed to login.  See login.defs(5) if you use the shadow suite.

       On  PAM  enabled  systems, it is used for the same purpose by pam_securetty(8) to restrict
       the terminals on which empty passwords are accepted.

FILES
