Hi, LCMan, I have been using mSecure. you can have everthing on there, banking and credit card info and passwords, vehicle info (vin, tire size), prescription/medical info, insurance info, etc. It's very user friendly and has a lot of categories to use. I, too, have many passwords for lots of different things and I don't always remember them all and I don't want to have them on a piece of paper that can get lost. The app itself allows for numerical password as well as a strong password. The price for the app is $2.99, but it has a 4 star rating with over 100 reviews. I sync it on my mSecure computer app so it's all backed up. There is no subscription cost to deal with either.
I was a little leery about having that private info on my phone, but with the phone passcode and the strong password for my mSecure app, I feel better about it.
My comment wasn't made because I took your post to be personal. However, it might have been more helpful if, rather than saying:
"I don't use anything. It is totally free"
you'd said:
"We use secure USB key for everything".
The OP wants something he can access on an iPhone, not a USB key that he needs to plug into a laptop.
If you don't use anything on your iPhone, I don't see why you felt the need to chip in to be honest.The title of the thread is : "A good password app for my 3GS"
