Buttercup: What it is and what it does
Buttercup is a cross-platform password vault that stores login credentials and other private data in encrypted archives. It uses strong 256-bit AES encryption to keep usernames, passwords, and related notes protected inside encrypted files. The app is built to run on multiple operating systems so you can access the same secured data from different devices.
Encryption and access controls
All entries in Buttercup are encrypted with industry-grade AES-256, ensuring that stored information cannot be read without the correct credentials. Access to the vaults is controlled with a single master password, which simplifies entry while keeping the data safe from unauthorized users.
Storage and synchronization options
Buttercup supports linking your vaults to several storage locations so you can back up and sync across devices:
- Google Drive (Drive)
- Dropbox
- WebDAV servers
- Local/internal device storage
These connections let you keep your encrypted files in the cloud or on local media and share protected documents when needed.
Usability and setup
The interface is designed to be straightforward, guiding users through creating a vault, adding items, and connecting storage services. Because only one master password is required, Buttercup aims to balance ease of use with strong security practices.
