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

Simple, open source, free and syncs flawlessly. Couldn't ask for more and it's nice to have control over my credentials. I use it on every device I have and every browser. I keep my credentials centrally on my own NAS for security and it is a very simple process. plus as it's open source, I have much more control to vendor it for myself and manage myself. I'm not sure why people keep having issues with it. It gives you every option necessary how and where you want to host your credentials.

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.

For some reason the offline feature doesn't work sometimes. Furthermore, the app doesn't support using local files as vaults. In light of these issues, I can't give the app 5 stars, but Buttercup is cross-platform, easy to use, open source, and the desktop app has every feature you could want.

What’s new
