Password managers have developed into important tools for businesses to keep all their passwords secure. They store company credentials in encrypted vaults, allow for easier sharing within teams and can be accessed via multiple devices.

While the benefits of password managers are undeniable, many options available are proprietary. Proprietary software refers to applications that have code designed and owned by a specific company. Under this setup, the code isn’t modifiable and can only be accessed by the vendor itself.

This is where open source password managers come in. Open source password managers make their code accessible to the public, allowing users to customize the software to suit their needs. Having publicly available source code also means vulnerabilities can be more easily spotted and corrected.

If you want to read more about the benefits of open source password managers, we have a great overview of its pros and cons here.

With that, I’ve created a list of the best open source password managers for teams and businesses.

KeePass is a popular pick for tech-savvy and privacy-focused users that prioritize customizability above all else. It’s completely free and utilizes its open source nature through its large suite of user-generated plugins. These plugins and extensions provide even more features to KeePass’ base functionality.

KeePass is the only offline password manager on this list, making it a good option for people who aren’t keen on having their passwords and other data stored on the cloud. While its user interface isn’t the most intuitive, it can be a powerful tool for users who want their password manager tailor-fit to their needs.

For businesses that want a comprehensive security solution, consider Proton Pass. Proton Pass is a password manager from security vendor Proton, which also offers encrypted mail, VPN and cloud storage services to customers. With this, Proton provides users and businesses an option to purchase not only a password manager but a bundle of other security services as well.

On its own, Proton Pass is a solid password manager. It’s end-to-end encrypted, has been independently audited and allows for secure sharing of company credentials.

I personally like its unique hide-my-email aliases feature, which creates randomly-generated email addresses for your different accounts, thereby protecting your main email address.


Why we chose Proton Pass

I picked Proton Pass because it’s part of Proton’s portfolio of security products. Businesses using their other services like ProtonMail and Proton VPN — or those looking to have an ecosystem of security services — should give Proton Pass a look.


Proton Pass has two tiers: Individuals and Businesses. For individuals, we get Proton Free, Proton Plus and Proton Unlimited. Here’s a quick overview of the individual plans:

  • Proton Free: Free; unlimited logins; 10 hide-my-email aliases vault sharing up to three people.

  • Pass Business: $2.99 per month, per user (annual); require 2FA for organization; Proton Sentinel program that provides specialized security support.
  • Enterprise: Contact Proton for pricing; customized feature set; bundle with other Proton services.

  • End-to-end encrypted note-taking.
  • Email aliases create unique emails to hide the main address.


  • User data protected by strong Swiss privacy laws.
  • Multiple plan options for different customers.

In terms of security, I appreciate Passbolt’s transparency and commitment to communication with its user base.

Why we chose Passbolt

I chose Passbolt for its management-focused features that could benefit larger businesses or teams. In particular, it offers tags management, granular access rights and role-based access control across its plans.

Passbolt also provides the option for businesses to either store their passwords on the Passbolt Cloud or to self-host. To me, having this choice makes Passbolt a viable option for different types of businesses with varying needs.

  • Passwords management and sharing.
  • Community plan is free for unlimited users.


  • Independently audited password manager.
  • Bug bounty for those who want to audit Passbolt code.
  • Option to self-host or store on the cloud.


  • May not be suited for smaller teams or businesses.
  • May require technical expertise to maximize.

How do I choose the best open source password manager for my business?

Choosing the best open source password manager will largely depend on your business’ structure and needs.

In terms of structure, smaller teams won’t need as many team-based features like granular access controls. In this case, you can look into offline password managers or cloud-based solutions that have simpler but more intuitive applications.

For larger businesses, you may want to invest in a password manager that includes management features that can handle hundreds of accounts and users. With thousands of credentials to sift through, having features like role-based access or tags management can save your business a lot of time and money.

Finally, consider cost in accordance with the features your business actually needs. If you’re looking for only a password manager, a mid-tier subscription will do the trick. But if you want a comprehensive solution, password managers bundled with other security software are worth looking into.

Review methodology

For this list of the best open source password managers, I prioritized looking at products with the best balance of password management features, pricing and real-world value. In particular, I looked at how each product mentioned could benefit a specific type of business or use case.

In terms of features, all the password managers above provide a healthy set of subscription options, viable two-factor authentication methods and support for a wide range of platforms.

While I had real-world experience with some of my picks above, I utilized user testimonials and third-party reviews to supplement my analysis of the options I have yet to test for myself.
