Buttercup is a simple password manager based on NodeJS. It’s an assistant for helping you store all of your login credentials. Buttercup helps you keep your accounts safe and assists you when you want to log in – all you need to do is remember just one password: your master password.
Buttercup uses very strong encryption to protect your sensitive details under a single master password.
Buttercup provides a secure way of storing your details, but it is only as secure as how you treat your master password and archive files.
Buttercup Desktop is written in JavaScript using the Electron framework.
Key Features
- Easy-to-use interfaces with basic concepts make storing and finding your login details trivial.
- Supports loading and saving credentials archives both locally and remotely.
- Strong 256bit AES encrypted archives that meet today’s security standards. Encryption is performed once the password has been salted and prepared with PBKDF2 at between 200-250k iterations.
- Buttercup Core features:
- Deltas for storing archive history.
- Conflict resolution and archive merging.
- AES CBC/GCM encryption w/ 256bit keys.
- SHA-256 keys using PBKDF2 derivation.
- SHA-256 HMAC authentication.
- GZip text compression.
- Archives store groups and entries in a simple hierarchy. Both groups and entries can be moved into other groups. Deleted items are trashed before being removed permanently.
- Basic merge conflict resolution.
- Global search feature – search for entries across all your unlocked archives.
- Archives in sidebar are sort-able.
- Import from other password managers: KeePass 2 archives, Lastpass archives, 1Password PIF files, and CSV files (general).
- Export Buttercup vaults to CSV format.
- Remote archives can be stored in a variety of service providers including Dropbox, ownCloud and Nextcloud (and others that support WebDAV, such as Yandex).
- Cross-platform support – runs in Linux, Windows, and macOS. There’s also support for iOS and Android. There’s extensions for Chrome and Firefox web browsers. For Linux, there’s 32-bit and 64-bit packages for Debian/Ubuntu and Fedora. There’s also an AppImage and a snap available.
- Internationalization support – Czech, Dutch, English, Farsi, French, German, Hungarian, Italian, Portuguese (Brazilian), Spanish, Russian, and Ukrainian.
