Can I have Passwordsafe on my old computer and also transfer it to my new one. i.e. have it on both of my computers? In my ideal world I would like to keep the information on a jump drive as well so that I can access my passwords on any computer. My old computer uses 32 bit Vista, my new one uses 64 bit Windows 7 Home Premium. If I can put Passwordsafe on a jump drive will it also work on a Mac as I have access to one of those as well. Thanks.
