Looks like someone from Google is working on a secret project which is called "Secrets for Android", a project yet available from Google Code only. Secrets for Android is an application to securely store and manage passwords and secrets on your Android phone. It uses techniques like strong encryption and auto-logout to help ensure that your secrets remain safe (assuming you use a good master password!). Should Secrets be running when your phone goes to sleep, you will be automatically logged out. The next time your phone wakes up, you'll need to re-enter your master password to continue. Switching to another application and returning to Secrets will also require you to re-enter your master password.
Context-sensitive tips guide you along through its operation, making it easy to use.
The first time you start Secrets, you'll be asked to choose, and then confirm, a master password. Subsequently, you will need to enter this password before any of your secrets will be revealed. After entering your master password, you see the secrets list. To add a new secret, press MENU and tap "Add". A secret can consists a description, an ID (for example a credit card number, a PIN (or password) and notes and all information fields are optional. Enter as much or as little as you like. A very secure PIN can be generated by pressing MENU and tapping on "Generate".
The main secrets list shows all of your secrets, ordered alphabetically by description. Each entry in the list shows the description, the Id or E-Mail address and the time and/or date of the last action that was performed on that secret. If your list of secrets is long, you can even filter it by typing on the keyboard. Only those secrets whose description begins with the typed letters will appear in the list.
Secrets for Android is open source using the Apache 2.0 license, so you can examine the code yourself, or modify it to your needs. Secrets is available in English and Chinese and only available from the project page at Google Code. Secrets for Android is a pretty simple but easy to use password manager which even allows to import and export lists.
