### NAME

pam_securetty - SecureTTY PAM module

### SYNOPSIS

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

### DESCRIPTION

The SecureTTY service module for PAM provides functionality 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.
