Buttercup – A Modern Password Manager for Linux

Buttercup is a cross-platform, free, and open-source password manager with which you can remotely access any of your accounts using a single master password. It features a modern minimal UI, password imports from 3rd-party apps, and basic merge conflict resolution.

There are already a handful of nice password managers in the market e.g. 1Password, but not everyone can readily afford its subscription service and are therefore left to struggle with lesser developed apps.

The developer rightly wrote that,

there’s no solution that, for free, offers credentials synchronisation across every platform with support for merge conflicts and a choice in hosting environments

Features in Buttercup

  • Beautiful modern UI.
  • Cross-platform and available as an extension for Google Chrome (and its derivatives).
  • Free and open-source.
  • Password and data encryption using modern algorithms.
  • Load and save credentials to archives stored both locally and remotely.
  • Store archives in service providers like Dropbox, ownCloud.
  • Basic merge conflict resolution.
  • Import passwords from other password managers including 1Password (.1pif) and KeePass(.kdbx), and LastPass (.csv)

At the time of writing, Buttercup is considered unstable because it is still under heavy development and the dev team has promised to always deliver timely updates and bug fixes so that you don’t have to worry about version malfunctions and security breaks.

Having used a hand full of password managers myself, I agree with the dev team that Buttercup is the password manager you deserve. If you’re searching for a reliable password manager that offers premium services for free then give Buttercup a test-drive and see if you’re not won over.

  1. Like others I am looking for an (open source) alternative to 1Passsword which I have used happily for some years. I like the look of Buttercup but have a problem with it. I have created/exported a “1pif” file from 1Password, and the “job done” message says there are 251 records, which is about right. But when I import it into Buttercup it is empty; no records. Nada. So, what next? Creating records one by one works fine.

  2. I love a good password manager. Enpass is my go to solution at the moment because of the cross platform availability but it’s not open source. The mobile client has a one time cost of $10 on each mobile platform which I paid gladly considering the competition’s prices and their unwillingness to support Linux. I automatically eliminated anything with cloud sync to the app vendor’s servers (e.g.: LastPass, Dashlane).. call me paranoid but I didn’t feel comfortable using those services.
    Anyway, this looks like a great alternative and if the devs will keep it open source even on mobile platforms I would definitely jump ship
