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
- OTP/2FA codes (adding and displaying)
- 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, Google Drive and WebDAV-enabled services.

No information regarding you or your archive is sent to us or any other service. No in-app analytics are used and we rely on the completely anonymous service analytics provided by Apple and Google. If you have any queries please consult our privacy policy.

Great open source password manager

Takes a little work to get started but it’s an excellent app. I am switching from 1pw to this and don’t notice any difference in functionality with auto fill, etc. Support open source!

Bug: Doesn’t save

If you edit an entry and add a field, click save, but NOT hit save a second time and then lock the vault, then the modification is not saved! There is no warning that the edits won’t be saved, and no one expects the items not to be saved after the first click on save! Easy to lose data with this app! Please fix and I will up the rating to 5.
