About this app

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 vault that you store where you want.

Buttercup vaults 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 vaults and credentials on every platform you use.

All information stored within Buttercup vaults 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):
- 2FA/OTP (TOTP) ingestion and display
- Store an unlimited number of login details
- Save your vault to a variety of storage providers
- Save your vaults locally to the device
- Open sites stored within the app by the touch of a button
- Open vaults auto-lock and close after 10 minutes of inactivity
- Vault contents hidden when app is put to background
- Ability to add multiple vaults
- Autofill passwords for login forms

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 vault is sent to us or any other service.

Ratings and reviews

I'm just starting to use this app. It seems like it has potential. Still, it seems like it's in a rough stage, as the UI is really rough. I do like the main homepage and the way the vault looks, though. I don't know if it's just me, but there is no import or export feature while using the local vault. I think having a local vault is a plus, and a reason to get this app. There are no other native open source password managers apps on iOS or Android that have full offline vault support (no cloud).

5 stars for desktop app, but the mobile app literally does everything but the one thing I actually want it to do. In the present state its useless without giving your passwords to the cloud. The only reason I selected buttercup over other password managers is that it is offline. Until this app can read local .bcup files I have for my laptop and desktop I consider it broken and does not deliver what the desktop version does, it cant even create local .bcup archives.

I use firefox for browser and I have few comments. Getting the prompt to use buttercup to fill the password is inconsistent most of the time it fades before I click anything. In your website you claim to have security overlay when app is minimized, that doesn't work. I can't load a local vault that I export it from my computer, no way to import it. The password generator generated password with lower and upper case without digits few times even though i only included these three. Good luck.
