With a Free LastPass account, sharing is limited to One-to-one sharing, where you can only share one item at a time with one other user.

Does the Premium version use a single vault so there's NO need to coordinate 2 vaults? Does the Premium version have significantly improved sharing so if necessary (presuming there are a bunch of restrictions on the free version) we'll be able to share EVERYTHING? Presuming she finds it better than Dashlane, she wants the Premium version - PRIMARILY in the hope that support would be significantly better if we give them money. Can I actually SHARE everything between the two PCs, or do I need to take a csv over to her system and just install it? Are we limited to sharing passwords or will we be able to share everything or JUST passwords? Will it share and syn bank accounts, credit cards, financial info, investment info and so on? Or is it JUST passwords? Getting it to my wife so she can see how it works and if she likes it better than Dashlane. It STILL makes me log in EVERY time I open the vault in the browser, but I think that's some browser setting (at least I hope so). I've finally gotten everything out of Dashlane and into Lastpass on my system.
