# Enable Password

If Use Password is turned on, a person attempting to post to the list will be required to enter a password. If Enable Posters List is also turned on, then users in the posters list will also be required to enter a password.

The password must be entered in the "Subject" field of the message and must be enclosed in brackets and colons as such [:password:].
