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 al-
lowed 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.
