SECURETTY(5)              (2020-06-09)               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_securetty(8) to restrict the terminals on which empty
          passwords are accepted.

     FILES
