I have used e-wallet, and it is a good app. And I have tried many others, too. But Mobipassword is the best password keeper I have ever used!! I think that it is the most secure, too. It does not keep a copy of your data on the desktop, it transfers it when you have your axim connected to your pc, and then removes it when you disconnect. When you have it connected and running on both your axim and pc, you can link your accounts to the web page you use to log in, and it will automatically log in for you!! It also has a great password generator built in. I highly recommend it. Check it out here ->

P.S. I am not a rep for the company, just very pleased with the product!
