Buttercup for Android is a free, open-source, cross-platform password manager. Its features include storing an unlimited number of login details, saving password archives to a variety of storage providers, opening sites stored within the app by the touch of a button, opening archives that auto-lock and close after 10 minutes of inactivity, and archiving contents hidden when the app is put to background. Buttercup is also available on Mac, Linux, Windows, and iOS, as well as Chrome and Firefox extensions.
Buttercup for Android was the brainchild of senior software engineers Sallar and Perry Mitchell.
