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.
