securetty — file which lists terminals from which root can log in
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.
