AES 256-bit encryption with this versatile and secure password manager.

Buttercup is a simple, yet elegant-looking password manager with an option to synchronize with your Dropbox account.

The main layout of this password manager is straightforward, allowing you to create groups and items within those groups such as bank account information, passwords or other web accounts.

Featured here in Buttercup is strong AES 256-bit encryption which makes it next-to-impossible to crack it. The items stored in the Buttercup database are behind a master password, a password which we should mention cannot be recovered if you lose it or forget it.

Cloud services that Buttercup supports include Dropbox, owncloud, nextcloud and WebDAV.

With all of that in mind, Buttercup is definitely a lovely-looking password manager and its synchronization tool means your password databases can also be saved to cloud services so you can retrieve them on multiple systems.
