Buttercup uses the strongest industry techniques to encrypt and store your details in a variety of locations of your choosing. Use Dropbox, Google Drive or a WebDAV connection to remotely host your archive for high accessibility. You can also connect local files when using the Desktop application (background). The extension also contains a full-featured vault editing interface so you can even use it as a standalone application. Manage your data using different item types (logins, websites, notes etc.) and even store securely-encrypted attachments (drag-and-drop files). Buttercup's browser extension allows you to easily log in to all of your online profiles and sites, is extremely secure, is easy to use and completely free of charge. We collect no data about you or any activities you perform. Keep your master password safe as it is the only way to open your archive and access your credentials. Newly detected logins will cause the extension to prompt you to save them - add all of your online authentication details to keep your accounts safe!

  • (2022-08-31) Mohamed: Very well done. Zero problems.
  • (2021-10-20) Dominik Pavlíček: Great password manager
  • (2021-07-15) Lokman Afandy: it is great but need importer for extensions so people can migrate easily
  • (2021-05-21) M Shah Omar: CPU load always peak whenever this plugin enabled. using chrome Version 90.0.4430.212 (Official Build) (x86_64)
  • (2021-03-04) S Abraham: I was struggling to find a decent KeePass extension. They all appear to be outdated and don't quite work. Buttercup was suggested. It's a GREAT replacement for LastPass on the desktop. Apps for Apple, Android, not as great depending on your preferences. It's not constantly running in the background, autofilling passwords with one tap. It appears that you actually have to open the app, find the username/password you need, then copy and paste. So, if you don't have as many needs on mobile (and you may not - so many of my services use biometrics, I only need this for the outliers!), Buttercup seems to be a good alternative.
  • (2021-02-19) Micha Cassola: Wow! Finally I can move away from LastPass. And you can build your own Team PW Manager functionality by just using another Vault and Master-Password and then sharing that with your Teams over DropBox or Google Drive (more coming soon I am sure). Really well thought out and already looks great too!
  • (2020-08-04) Marc Lara: It was great, now it is very unstable and always crash
  • (2020-07-29) Aurélie Grebe: This password manager works great and gives you complete control over your passwords!
  • (2020-01-23) cwkktt: not simple, personal to use. But could have a try. If i met you before bitwarden, i will choose you. But i have installed both you and bitwarden.
  • (2020-01-03) Ion Staver: Does not keep the vault unlocked when closing and reopening the browser although the extension is set to auto-unlock.
  • (2019-10-29) Walmer R: I love this password manager. Its open source, cross-platform and most importantly secured. I was looking for a good alternative that would give me more control over how my passwords are kept secured. The only problem is that is that the save password option when you fill out a form isn't working.
  • (2019-08-05) Dumitru Maros: Imi place foarte tare, este opensource si bun
  • (2019-05-10) Christian Elbrianno: One of the most simple and easy-to-use cross-platform password manager.
  • (2019-03-20) Andreas Kosmo: Buttercup itself is a good thing, and also the extension is quite usable. Anyhow there are crucial things that I need to address because they simply annoy me: 1) they change too much of the markup which then could easily be copied into other markup (when editing HTML in the browser). 2) they add ugly CSS classes to forms so some forms around the web will look ugly if they don't make a form unusable in some cases. 3) Buttercup keeps on asking to save a password and there is no way to tell the extensions "never on this page" 4) the Buttercup extension should be deactivatable from the toolbar, so it might be possible to turn it off quickly. 5) Even better, buttercup should stop working on pages that have been marked as "never ask again if I want to save my password for this site". So there's a long way to go – though it's a good start.
  • (2019-02-15) Mohamed Diarra: superbe, merci au developpeur
  • (2018-11-06) Ferran Buireu: Excepcional, tanto a nivel de diseño como de facilidad de uso. Además es open-source. Sin lugar a dudas se come a la competencia en cuanto a filosofia y características. Si bien aún le queda trabajo por hacer y características por mejorar (widget de los inputs por ejemplo) tiene muy buena pinta.
  • (2018-02-05) Bigattck Firecat: only saves it on other cloud serves. you need to add it and many unnecessary stuff
  • (2017-09-02) Kikoo Kikoo: Il fallait bien le noter non ;)
  • (2017-04-20) Stefan Moises: Nice Chrome integration, easy to use, Buttercup is a cool password manager with Electron client apps, Cloud support etc. which allows you to use your own infrastructure to store the password archives.

  • (2021-01-21, v:2.24.1) Charles Heltzel: Autologon not working on some sites
    I cannot get the autologon to work on some of my banking sites. The Buttercup logo does not appear near the Id and Password fields. Occurs on Ubuntu 20.10 using Chrome, Chromium and Firefox browsers (all at current versions).
  • (2020-09-03, v:2.21.0) Bax De Riv: Trouble with Google Drive
    Since the update of google drive there is no longer the possibility from the browser to open the vault. There is always an error message "Failed unlocking archive". Unable to unlock archive (ddc24b3b-4bd6-4e2c-994d-4ddccf4193be): Unlocking archive source (ddc24b3b-4bd6-4e2c-994d-4ddccf4193be) failed: Failed unlocking source: Failed fetching Google Drive vault: n.refreshToken is not a function". Even after the vault has been reset, the problem comes back. On the desktop version there is no problem. Thanks for watching

  • (2018-07-14, v:1.10.0) Honza Pelikán: Automatic startup
    Hello, since last updates Buttecup in every Chrome launch automatically open new tab to Unlock archive. That's a unwanted behaviour, at least for me. Is it possible add an option to enable or disable this feature? Thanks.
  • (2017-11-28, v:0.14.2) Cori Haws (Stealthbird97): NextCloud
    There is no nextcloud option for sync in the extension, like there is in the desktop and mobile aps.
