SECURETTY(5) Linux Programmer's Manual SECURETTY(5)
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.
