Warp Terminal

Password manager is an incredibly helpful utility, and there's no shortage of options when finding one.

Your smartphone manufacturer offers one, the browser offers another, antivirus applications include one, and then there are other third-party offerings. You can choose to use any password manager of your choice as per your convenience.

But, what if you prefer open-source password managers? Should you give them a try over proprietary ones? What are the options you have?

Here, let me highlight all the essentials.

Why Should You Pick an Open-Source Password Manager?

A password manager is a critical utility which stores sensitive data, including:

  • Account credentials
  • Secure notes
  • Recovery codes
  • 2FA tokens (in some cases)

So, it is important to use a password manager offering the best privacy and security.

And, with an open-source option, you get better transparency and more people to work together to keep the password manager secure.

Sure, if you want to contribute, review, and improve the password manager, you need a bit of technical skills. But, even if you do not have the time to do anything, the community of users and other developers will try to verify the claims by the company.

That is the advantage you get with an open-source password manager.

With a proprietary solution, you will have to trust the company, and will have no other way to verify the claims from your side.

Considering the benefits of choosing an open-source tool for security, I have picked some of the most loved password managers for all kinds of users.

1. KeePass

KeePass is an impressive open-source password manager for Windows users. You can try running the Windows app on Linux using Wine.

It is a local-only password manager where you store all your passwords in one database. The database is encrypted and protected with a master key that you set (do not forget it).

Of course, you can decide to sync the database file on any cloud storage of your choice (only if you require it). Otherwise, it is more secure to have your data on your system than on the cloud.

You can pick to install KeePass or use the portable version through a USB stick. It features many useful functionalities like adding attachments, sorting, the ability to import and export, and many more.


  • Local-only
  • Portable version available
  • Import/export supported
  • Password organization through groups/sorting
  • Plugins to enhance feature set

2. Bitwarden
