Buttercup is an open-source password manager, available on all major platforms. It helps you track and store your login information for any service you use - personal or for work - in a securely encrypted archive that you store where you want.

Buttercup archives contain groups and entries so that you can easily manage your login credentials. There’s also a desktop application and browser extension available, so you can access your archives and credentials on every platform you use.

All information stored within Buttercup archives is private and encrypted - available only to those with your master password. Keep this password secret and don’t use it for any other login! Once you have your login details stored within Buttercup, you can concentrate on remembering only the 1 password (for Buttercup) - all other passwords can be long, gibberish text to increase security, and you don’t have to remember them!

Buttercup’s features (non-exhaustive):
- Store an unlimited number of login details
- Save your archive to a variety of storage providers
- Autofill login forms
- Open sites stored within the app by the touch of a button
- Open archives auto-lock and close after 10 minutes of inactivity
- Unlock archives using fingerprint authentication (or FaceID on supporting iPhones)
- Archive contents hidden when app is put to background
- Ability to add multiple archives
- Open archives in offline mode
- Search the contents of open vaults

Buttercup is designed to be used with free-to-use cloud storage providers, such as Dropbox, ownCloud, Nextcloud, and other WebDAV-enabled services.

No information regarding you or your archive is sent to us or any other service. We do track analytics, which include only the first 2 parts of your IP address (for location breakdown by country only) and the version and type of your operating system. No personally identifiable information is collected, and we do not sell or share this information with anyone. If you have any queries please read our privacy policy.

What’s New

Version 1.8.1

We've fixed a couple of bugs that crept in via the last release, related to repeated prompts for authentication when working with your vaults. We've also patched Dropbox + ownCloud/Nextcloud/WebDAV so that creating vaults works again.
