## 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)](https://www.chedong.com/phpMan.php/man/login/1/markdown) to restrict the terminals on which root is  allowed
       to login.  See [**login.defs**(5)](https://www.chedong.com/phpMan.php/man/login.defs/5/markdown) if you use the shadow suite.

       On  PAM  enabled systems, it is used for the same purpose by **pam**___**[securetty**(8)](https://www.chedong.com/phpMan.php/man/securetty/8/markdown) to restrict the
       terminals on which empty passwords are accepted.
