securetty - list of terminals on which root is allowed to login
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.
