Can the RDF file be used on a computer that cannot install password maker? In other words, How can you obtain the generated password to manually input on a public computer?
No reason you cannot install the extension (unless the computer doesn't even have Firefox), but the other option is to use the online version - but no, you cannot, at this time, use your RDF file withe the online version - you would have to know your settings for each account.
There is a FR (Feature Request) to be able to
Import your Settings into the Online VErsion, and one to
sync your settings with the online version (and optionally with any other PWM installation you use), so you might want to go votes for one or both (and any others that you'd like to see implemented)...
