This app was exactly what I was looking for--all I needed was one convenient location to store my usernames and passwords. Nearly every website requires a login name and password and the requirements are always different "only letters", "must include numbers 0-9", "no special characters '?, _, -, etc"--and it got to be very confusing to remember them all. Every time I write one down, I lost it. If I keep a list in my desk drawer, I'm not at home when I need one. Resetting them and having to check my email repeatedly for "Password Reminders" got VERY OLD. Basically, it was my savior for about three months. Now for some reason, it won't let me open the app. I have the latest version available installed and I'm afraid to make any moves to try to fix it because it's the only place that ALL of my passwords are stored. I'm currently trying to pay some bills online and it's quite a headache trying to figure out my passwords for each one considering they each differ from the other by only one or two specific characters. If you get this app, be prepared for it to suddenly block you out. It might be convenient when you're not at home and need a reminder to login to a site, but make sure you write them all down on paper somewhere too or you will end up frustrated like me!
