29 | .SH DESCRIPTION |
| 30 | The file | |
| 31 | .I /etc/securetty | |
| 520c3a8b | 32 | contains the names of terminals |
| fea681da MK |
33 | (one per line, without leading |
| 34 | .IR /dev/ ) | |
| 520c3a8b SA |
35 | which are considered secure for the transmission of certain authentication |
| 36 | tokens. | |
| 11ac5b51 | 37 | .PP |
| 520c3a8b SA |
38 | It is used by (some versions of) |
| 39 | .BR login (1) | |
| 40 | to restrict the terminals | |
| fea681da MK |
41 | on which root is allowed to login. |
| 42 | See | |
| 43 | .BR login.defs (5) | |
| 44 | if you use the shadow suite. | |
| 11ac5b51 | 45 | .PP |
| 520c3a8b SA |
46 | On PAM enabled systems, it is used for the same purpose by |
| 47 | .BR pam_securetty (8) | |
| 48 | to restrict the terminals on which empty passwords are accepted. | |
