SECURETTY(5) Linux Programmer's Manual SECURETTY(5)
NAME
securetty - list of terminals on which root is allowed to login
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_se-
curetty(8) to restrict the terminals on which empty passwords are ac-
cepted.
