You can generate a Portable Page to load and run in any browser when this extension is unavailable. It is similar to the online tool, but also knows your site tags and per-site option settings.
When you select one of your site tags in the drop-down list at the top it applies the appropriate options. The site tags and options known to the page represent a snapshot of what had been saved by the Password Hasher extension prior to generating the page. It serves as a useful of backup for your site tags and options. For security, the master key(s) are never saved in the page.
Make copies of the generated file to place on USB keys, servers, and other systems. You'll be able to log in from anywhere, whether or not the Password Hasher is installed, and whether or not you're running Firefox.
