NAME

6       securetty - file which lists terminals from which root can log in
7

DESCRIPTION

9       The  file /etc/securetty contains the names of terminals (one per line,
10       without leading /dev/) which are considered secure for the transmission
11       of certain authentication tokens.
12
13       It  is used by (some versions of) login(1) to restrict the terminals on
14       which root is allowed to login.   See  login.defs(5)  if  you  use  the
15       shadow suite.
16
17       On   PAM   enabled  systems,  it  is  used  for  the  same  purpose  by
18       pam_securetty(8) to restrict the terminals on which empty passwords are
19       accepted.
