Security Levels

Light maximizes convenience by guessing site tags, remembering entries, and revealing fields as plain text. It is secure from remote hackers, but less secure from people with physical access to your machine and browser.
Medium improves protection by hiding the hash word and forcing you to re-enter the master key each time. This is the default.
Heavy maximizes security by remembering nothing and hiding everything. You must enter the site tag and master key each time and manually unmask fields to see their content.
Custom allows you to specify individual security options. Tip - choose light, medium or heavy before selecting custom to start with a reasonable set of checked options.

Display Options

Password field markers are small symbols inserted next to password fields for one-click access to the Password Hasher dialog.
Password unmasking markers are small symbols inserted next to password fields for one-click unmasking (revealing as plain text) of password fields.
Guess full domain causes guessed site tags to use the entire domain name, e.g. including ".com", ".org", etc., making it easier to have separate logins for sites sharing the same base name. It does result in longer site tags, when you have to type them.

Default Requirements

These settings affect the default options for assuring generated hash words satisfy certain requirements.

Digit forces hash words to have at least one digit character.
Punctuation forces hash words to have at least one punctuation character.
Both upper and lower-case letters forces hash words to have at least one of each case letter.

Default Size

This setting chooses the default hash word length, i.e. number of characters.

Portable Page

This button produces a self-contained/portable web page to generate hash words when this extension is unavailable. It asks you where to save the file and then loads it in a browser tab. More information is available in the FAQ, the Portable help page, and notes on the bottom of the generated portable page.
