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 transmis- sion 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
