Masterkey

Masterkey is an easy to use password manager for the Android platform. Designed primarily as a simple password keeper, it can easily be used to house a variety of sensitive information and leverages encryption to ensure data security. It requires no permissions unless you decide to import or export passwords in CSV format.

Today, password managers are built into most operating systems and web browsers. If you're like me, sometimes you would prefer to store your passwords on your device and not in the cloud. That's why I developed Masterkey in the very early days of the Android OS. That's also why I keep maintaining it; because I use it. - Will
