Window's "Live Mesh" is also free and syncs among many computers. The drawback with passwordmaker however is when you are away from the typical computers (home/ office) which have been configured. There are times when you are out in the public sector (airports, hotels, etc) when you need to access the system using other computers. In order to log-in with passwords you need to import the RDF file for non default accounts before generating the passwords. It would be simpler to go to a website, pull down the bookmark and have Passwordmaker begin the password generation, filling in the remaining inputs, much like LastPass or equiv. The drawback with programs such as LassPass is that the encrypted password files exist on some website.
Another system used by RoboForm are bookmarklets which allow users to add when browsing on unfamiliar computers per session. The bookmarklets, once logged off, erase the session cache, etc., leaving the computer without any vital information. Perhaps PasswordMaker can adapt this feature.
