Last Updated by John Bennet on September 01, 2021

Open source password managers are the best way to store the passwords and credentials on your computer without worrying about hackers getting their hands on them.

Using a password manager might be the best way to store your passwords and credentials online, but you have to be careful about which ones you use. You need a password manager that’s user-friendly and secure so that your data remains safe.

It can prove a daunting task to find the best password manager in a crowded market, so we’ve done the work for you. Read on to find out more about open source password managers, why you should use one and which are the best.

Why You Need Open Source

When it comes to protecting your password, you might think you have to pay a lot of money for commercial protection software, but that’s simply not the case. Most are free.

Open source simply means that the software isn’t finished. Unlike traditional programs, these open source password managers are improved upon by anyone that finds a solution to a problem. That allows users to detect errors in the code and patch them up, which can further protect you from hackers.

On top of that, open source password managers are customizable. They allow you to create your own plug-in solutions that wouldn’t be a part of commercial options.

Our favorite part about a open source password manager is that they are free. Of course, there’s the option to donate to the developers but they shouldn’t cost a dime.

Let’s take a look at the top 10 open source password managers available today.

1 KeePass

KeePass password manager
Dominik Reichl developed KeePass in 2003. It’s a Windows-based manager that also offers compatibility with Linux and macOS. They utilize bank-level encryption with SHA-256 hashing. In addition, they have multiple options for database imports and exports, remain fully customizable, have searchable password groups, and provide a strong password generator.

Because the software is portable, there’s no installation. The entire database remains in a single file, so transferring it is hassle-free. On top of that, it utilizes a two-factor authentication for superior security.

2 Clipperz

Clipperz mobile password manager
What’s unique about Clipperz is that it works from mobile browsers. This open source single page password manager supports many import and export options and has plenty of offline features.

It’s easy to login to sites from Clipperz’s database with the quick authentication process. On top of that, the software encrypts everything that leaves the vault. Because it uses a 128-bit cryptographic system, you don’t have to worry about your stored information.

3 Passbolt

If you think that an open source program can’t have the features of a commercial option, it’s time to look at Passbolt. This open source manager offers an easy-to-use interface but still contains many features for a robust system.

The passwords are completely searchable and editable, plus it’s easy to share with trusted people or copy them to your clipboard. There’s also a built-in generator and evaluation tool. The neat thing about Passbolt is that they send out e-mail notifications to keep you updated about the status of your account.

Because it’s open source, there are still things in the works. Users continue to upgrade the import and export tools, autofill, plus two-factor authentication. For now, you can use it with Firefox and Chrome with ease.

4 Padlock

5 Bitwarden

Bitwarden password manager
Bitwarden is one of the more well known password managers in our group. It’s comparable to a commercial product thanks to its visual appeal and set of features. If you didn’t know better, you would think it was a top-tier commercial manager.

It’s also simple to setup multiple credential collections. All of the data receives AES-256 encryption for your peace of mind. The software also provides free plans or paid for options depending on how many features you need.

6 LessPass

The software stores three types of data: credit card numbers, passwords, plus general value pairs. It’s also easily expandable to include other entry types as needed.

Final Thought
