Buttercup for Mobile
iOS, Android
Take your login credentials wherever you go by installing the free iOS or Android app on your phone. Buttercup mobile gives you access to the same vaults you use on the desktop application and browser extension, so your newly added details can be seen on all of your devices.
Buttercup’s mobile applications employ similar safety techniques to banking applications, such as auto-lock and a security overlay when the app is minimized.
Buttercup for Browsers
Chrome, Firefox, Edge
Note: the extension requires the Buttercup desktop application version 2.26 or later be installed and running, at least in the background. This browser addon uses an encrypted connection with the desktop application to transfer vault credentials during login and saving. This addon cannot function without the desktop application.
