I do 99% of my web browsing, online shopping etc on my iPad (3G, ipad2). I'll go weeks at a time without sitting down to a desktop.

I've been doing a lot of reading but not really narrowing down my list yet!

I'm looking for a password manager that will tick the following boxes:

Works really well on the iPad, with all of its features, settings etc available.

Generates passwords where you can force it to use a certain length, not use special characters etc (eg for banking sites that insist the password has to be 8 characters)

Will be good at filling in password fields in apps and browsers.

Can be backed up/synced/exported.

Not really keen on a separate browser - if possible I want to keep using ios Safari (or maybe ios Chrome).

Can be used sometimes different non-trusted work pcs, where I won't be able to install software (so maybe a usb stick with the program & vault on it?)

Happy to pay ~USD 20 or so.

I'm posting this in the ios forum as I'm really keen to only hear from heavy ipad users. (The usage is heavy, not the user!)
