The dictionary is only used once to generate master password. Then it derives site-specific keys with PBKDF2 from it. You can skip pz-master and use your own master password, but make sure it has enough entropy.<p>@burrows: I think there&#x27;s modulo bias here: <a href="https:&#x2F;&#x2F;github.com&#x2F;burrows-labs&#x2F;pz&#x2F;blob&#x2F;master&#x2F;pz-master#L11" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;burrows-labs&#x2F;pz&#x2F;blob&#x2F;master&#x2F;pz-master#L11</a> It probably doesn&#x27;t matter much, but the displayed entropy estimate won&#x27;t be exact.
