Password edit

This is a Drupal 7 module, it provides a password field, then anonymous users can create/edit the node with the field.

For login users, the password filed would automatically disappear.

You may want to use this field when:
your node can be created/edited by anonymous, and want a password to protect it.
you want to make a yellow page sites, and users doesn't need to login/register to post contents, but also can edit the content by their own.
