      [service-name] module-type control-flag pam_securetty [options]


      The SecureTTY service module for PAM, pam_securetty provides functional‐
      ity for only one PAM category: account management.  In terms of the
      module-type parameter, this is the “account” feature.  It also provides
      null functions for authentication and session management.
    SecureTTY Account Management Module
      The SecureTTY account management component (pam_sm_acct_mgmt()), returns
      failure if the user is attempting to authenticate as superuser, and the
      process is attached to an insecure TTY.  In all other cases, the module
      returns success.
      A TTY is considered secure if it is listed in /etc/ttys and has the
      TTY_SECURE flag set.
      The following options may be passed to the authentication module:
      debug    syslog(3) debugging information at LOG_DEBUG level.
      no_warn  suppress warning messages to the user.  These messages include
               reasons why the user’s authentication attempt was declined.
      getttynam(3), syslog(3), pam.conf(5), ttys(5), pam(8)
