Masterkey is an easy to use password manager for the Android platform. Designed primarily as a password keeper, it can easily be used to house a variety of sensitive information.

Masterkey's password vault is stored locally on your phone for maximum security. For added protection, all data within the database is encrypted using AES encryption. Access to the Masterkey app is protected by a user supplied password, set the first time the app is run.

Masterkey offers the following features:
* Local storage, requesting no network access that could be used to compromise passwords.
* Internal database encryption.
* Backup & restore using the SD card, and an additional layer of encryption using a user supplied password.
* Random password generation.
* Ability to copy passwords to the device's clipboard.
* Option to mask passwords in the list so that passwords are not displayed on the screen.

Version 1.08 addresses an issue some users were reporting in regards to data loss after upgrading their phones from Android 2.2 to Android 2.3.3. Users on Android 2.2 are strongly encouraged to upgrade to v1.08 of Masterkey in order to avoid data corruption when upgrading the phone OS.

Full documentation of Masterkey's features can be found on our website:

    Sucks!! It takes forever to pull up my list of passwords; it almost always forces a close; keeps saying I have the wrong password to log in. REFUND!

    Updated to the version 1.10 and lost all of my previous data. I did try to "restore" from SD card... NOTHING!! If I don't find a way to restore or help from the software writers I am dumping this application. It had 4 and 1/2 stars until today.
