# 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.
