There is such an option in the Text Field Properties box! It forces data entered to display as asterisks (unfortunately not bullets...}

I quote from Acrobat Help:

Text fields can be set up to accept user input, to display text strings, and to allow multiple lines of text. You can also set a wide variety of text field properties, such as limiting the number of characters a user can type into the field, and displaying lines between each character inside the text field.

Note: Some property settings are dependent on others. For example, you cannot check the spelling of a password field or a field used for file selection. These options appear unavailable. You must deselect the check spelling option before you can select the password or field used for file selection options.
