Secure "password vault"

Not sure if this is the right place to ask this. I want a free package that encrypts passwords etc and stores them in the "cloud"', which is equally accessible from Windows, OSX, iOS and Android. I'm sure such a thing exists, but I also want it to be functional and widely recommended. Any offers?

And it must also be fully up-dateable from all of these platforms.

I guess this is as good a place as any to ask... however, I doubt you're going to find such an application for free. "1Password" does want you want, but it's not free. If you do find an application that can do all that for free, please share it with us.

I'm sure our spammers from China, Pakistan, Russia and the Ukraine that would like access to all your info will be all over this one.

I don't know about IOS but it does the others: https://lastpass.com/

Thanks. Like others before me I should have said "ideally free"
