Crypto lets you store your user names and passwords on your phone, and encrypts the data based on a password you enter. The free version is limited to 3 entries. If you forget your Crypto password, you will not be able to get read your data and even we cannot recover your data if you forget your password.
*Even though your passwords are encrypted, if you lose your phone, the only safe course of action is to change all the passwords stored on your phone. Even when the best encryption possible is used, a really determined hacker can break it given enough time.
