PageOnce was an application we didn't pay much attention to initially. It sounded like fluff and was just another speck in the endless wave that is Web 2.0. But upon closer examination, it turned out that what we had here was actually something of value.
PageOnce lets you set up a slew of different accounts - NetFlix, credit cards, Facebook, gas bills, cable bills, LinkedIn, webmail, etc. - and access all of this information on one page. The app securely stores your logins and passwords to thousands of sites that you indicate you use, and then displays information from them in a condensed and customized format. One key to rule them all, eh?
If you're worried about security, the cool thing with PageOnce is that if your phone gets stolen you can easily log in to the website from any computer and have all your information blocked from iPhone and iPod Touch access. This means that you won't really compromise anything more than you would if you had lost your wallet, the advantage here is that you only have to call one number.
PageOnce is a really powerful app that you can do a lot with. You'd be hard pressed to find less than two functions that it could do for you, making this app a highly recommended one. Due to the security issues and straight out fear that people have with putting too much information in one place, we're going to have to keep this just under our must have iPhone apps.
