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.
