5 Best Password Managers for Firefox in 2021 (with Coupons)

Short on time? Here’s the best password manager for Firefox:

I tested every single password manager on the market to find the best ones for Firefox. I only managed to find 5 which were really good — ones that integrate seamlessly with Firefox, provide high security, are easy-to-use, and come with additional features.

Firefox does have a built-in password manager (Lockwise), but it’s pretty limited — it generates weak passwords (without any special characters), doesn’t fill out web forms accurately, and lacks essential features like password sharing.

Lockwise can’t compete with the third-party password managers on this list, which have things like:

  • Data synchronization — Sync data across multiple devices, operating systems, and browsers.
  • Two-factor authentication (2FA) — Verifies your identity with a second secure form of identification like one-time password authenticators, USB keys, or biometric scanners.
  • Excellent auto-filling capabilities — Auto-fills data with just one click upon entering a site with a login field.
  • Secure password sharing — Shares passwords with one or many other users.
  • Password auditing — Audits the quality and strength of your passwords and flags weak and reused ones that need to be changed.
  • Secure file storage — Stores notes, documents, and credit card information.
  • Breach monitoring — Scans the dark web for logins and sensitive personal data and notifies you if your identity has been breached.
  • And a lot more…

So, how do you choose the right password manager for you? I compared and ranked the best password managers for Firefox in 2021 based on their security features, additional protections, usability, and overall value.

Quick summary of the best password managers for Firefox in 2021:

How I Rated the Best Password Managers for Firefox

I tested each password manager using Firefox on my PC, MacBook Pro, Samsung Galaxy, and iPad 9 to make good recommendations for all Firefox users, regardless of the operating system or device they’re using.

Here’s what I looked for:

  • Security. I made sure each program on my list has 256-bit AES encryption or better. I also gave extra points for providing additional security features like two-factor authentication (2FA), password auditing, and breach monitoring.
  • Convenience. I looked for password managers that save, fill, and even replace passwords automatically. Additionally, an intuitive user interface, good multi-platform integration, and a well-designed Firefox extension all contributed to my decision-making process.
  • Customer service. I made sure that each customer support team could provide me with responsive, relevant, and useful support. Most password managers offer email support, but I gave extra points for phone support and live chat support.
  • Additional features. Many companies advertise extra features like automatic password changers, breach monitoring, and encrypted messaging. I tested each of them to ensure that they actually work as advertised and that they add to the overall functionality of the product.
  • Value. Every password manager on my list is competitively priced compared to other products on the market. I gave extra points for free trials and money-back guarantees.

🥇1. Dashlane — Best Overall Password Manager for Firefox in 2021

🥇1. <a href="" title="Dashlane" rel="sponsored noopener norefferer" target="_blank" data-btn-name="Affiliate Link - 213336" data-btn-indexed="1">Dashlane</a> — Best Overall Password Manager for Firefox in 2021

Dashlane is my favorite Firefox password manager in 2021 — it’s very easy-to-use, it protects user data with unbreakable 256-bit AES encryption, a zero-knowledge policy, and a wide range of 2FA options, and it comes with tons of extras.

Dashlane’s Firefox extension is excellent — during my tests, I found it very simple to generate and save new passwords, auto-fill logins, share passwords with other users, and fill out advanced web forms that even Firefox’s Lockwise was unable to fill out!

Dashlane also has a lot of additional features, including:

  • One-click password changer.
  • Virtual private network (VPN).
  • Dark web monitoring.
  • 1 GB cloud storage.
  • Emergency access.
  • Identity theft protection (US users only).

I really like Dashlane’s one-click password changer which works across 300+ popular sites — if you have accounts on some of those sites, Dashlane can change all of them at once with just one click. With other password managers, you have to change passwords manually, one at a time, so this feature is very useful (and saves a ton of time!).

I also love Dashlane’s VPN — Dashlane is the only password manager with an integrated VPN. This VPN provides a 100% secure internet connection as well as access to geo-restricted content around the globe. In my tests, Dashlane’s VPN was as fast as standalone VPNs, allowing me to watch videos without any buffering or lagging even when I was connected to very far away servers.

Dashlane Free only runs on 1 device, stores up to 50 passwords, and lets you share up to 5 accounts. Dashlane Essentials adds unlimited password storage, unlimited password sharing, and the automatic password changer, but it can only be used on 2 devices. Dashlane Premium adds syncing across multiple devices, a VPN (with unlimited data), dark web monitoring, and 1 GB cloud storage. Dashlane Premium Plus also includes identity theft protection, but it’s only available to US users. Dashlane has a family plan that comes with all of the features included in the Premium plan, plus 5 additional licenses and a family management dashboard.

Bottom Line:

Dashlane is the best Firefox password manager I tested. It offers an excellent balance of high-level security and convenience, along with additional features like a one-click password changer, a VPN (with unlimited data), and dark web monitoring. Dashlane’s Firefox extension is very user-friendly and intuitive, makes generating and saving logins very easy, and auto-fills passwords and other web forms with perfect accuracy. Dashlane Free offers a 30-day free trial of the Premium plan, and all paid plans come with a risk-free 30-day money-back guarantee.

🥈2. Keeper — High-Security Features + Encrypted Chat

🥈2. <a href="" title="Keeper" rel="sponsored noopener norefferer" target="_blank" data-btn-name="Affiliate Link - 213359" data-btn-indexed="1">Keeper</a> — High-Security Features + Encrypted Chat

Keeper is a highly secure, feature-rich password manager — it uses advanced encryption, supports a wide range of MFA options (including biometric login), and has all the features I expect to see in a premium password manager.

Keeper’s Firefox extension is also pretty good — during my tests, I was able to seamlessly generate new passwords and save and auto-fill both logins and payment details. While Keeper’s Firefox extension isn’t as functional as the desktop or mobile apps, it works as promised and is very intuitive and simple to use.

Keeper also has a lot of advanced features, such as:

  • Encrypted messaging app (KeeperChat).
  • Dark web monitoring (BreachWatch).
  • Encrypted cloud storage (10 GB).
  • Password auditing.

One of the things I like the most about Keeper is that it has an encrypted messaging app — this unique feature lets you send encrypted messages, photos, and videos to other users, retract messages, and set self-destruct timers.

Keeper is also a great choice for users looking for lots of cloud storage — Keeper provides you with as much as 10 GB cloud storage, which is a lot more than all of the password managers I tested (Dashlane and LastPass both give only 1 GB cloud storage).

Keeper has lots of plans to choose from (including a really limited free version). Keeper Unlimited has unlimited password storage, multi-device sync, MFA, password sharing, and emergency access. Keeper Family adds 5 licenses and 10 GB cloud storage. And there are also various bundles that include the encrypted messaging app, dark web monitoring, and additional cloud storage (up to 100 GB!).

Bottom Line

Keeper is a really good password manager with a lot of high-security features — plus standout features like an encrypted messaging app, dark web monitoring, and 10 GB of cloud storage (more than all of the other products on this list!). Keeeper’s Firefox extension works well and is easy to use, but it lacks a lot of the features included in the desktop app. Keeper has a wide range of plans to choose from, and you can try out its premium features with a 30-day free trial.

🥉3. RoboForm — Best for Advanced Form-Filling Capabilities

🥉3. <a href="" title="RoboForm" rel="sponsored noopener norefferer" target="_blank" data-btn-name="Affiliate Link - 213367" data-btn-indexed="1">RoboForm</a> — Best for Advanced Form-Filling Capabilities

RoboForm is secure, intuitive, and has the best form-filling capabilities on the market.

To make form-filling as easy and straightforward as possible, RoboForm has 7 different templates for all kinds of web forms (passports, credit cards, vehicle registration…) — plus a customizable template that you can personalize to fit your needs.

I tested RoboForm’s form-filling capabilities in Firefox, and I was very impressed with how accurately RoboForm completed the most complex web forms with dozens of different fields.

RoboForm also has:

  • Unlimited passwords across unlimited devices.
  • Two-factor authentication.
  • Password sharing.
  • Password auditing.
  • Secure cloud backup.
  • Secure bookmarks storage.
  • Emergency access.

The secure bookmarks storage is my favorite RoboForm feature — it encrypts, organizes, and syncs all of your bookmarks, so you can easily access the sites you saved from any device (this is a pretty cool feature that no other password manager on this list offers).

I also like that RoboForm lets you save application passwords — when I opened Skype on my desktop, RoboForm popped up and offered to save my Skype login and password, the same way it offers to save a new website login.

RoboForm Free has unlimited password storage on 1 device, form-filling, password auditing, and bookmarks storage. Users looking for multi-device coverage should consider RoboForm Everywhere, which also adds 2FA, cloud backup, and emergency access. RoboForm Everywhere Family is the same, but it covers up to 5 users.

Bottom Line

RoboForm has excellent form-filling capabilities — it auto-fills complex web forms without errors in just one click. RoboForm’s Firefox extension is good, too — it’s user-friendly and includes all of the essential password management features like saving and auto-filling passwords. RoboForm also has 2FA, password auditing, secure bookmarks storage, application logins, and emergency access. All RoboForm purchases include a 30-day money-back guarantee.

4. LastPass — Best Free Features for Firefox Users

4. <a href="" title="LastPass" rel="sponsored noopener norefferer" target="_blank" data-btn-name="Affiliate Link - 213352" data-btn-indexed="1">LastPass</a> — Best Free Features for Firefox Users

LastPass has a good free plan — it has strong security, an intuitive Firefox browser extension, and unlimited password storage across an unlimited number of either desktop or mobile devices (but not both).

During my tests, LastPass’s browser extension for Firefox worked really well. I had no problems understanding and accessing all of the provided features, and I was particularly impressed with its auto-filling functionality that worked flawlessly every time I navigated to a login field or web form.

LastPass’s free plan comes with:

  • Basic multi-factor authentication (MFA).
  • One-to-one password sharing.
  • Automatic password changer.
  • Password auditing.
  • One-time password generator.

I really like LastPass’s automatic password changer – I could automatically change my passwords for some sites without having to visit the sites and manually change the passwords (it works across 70 sites). While I prefer Dashlane’s automatic password changer, which covers more sites and is easier to use, I think it’s really cool that LastPass has introduced this feature as well (Dashlane and LastPass are the only password managers with automatic password changers).

Upgrading to LastPass Premium brings you additional features like syncing across all devices, password sharing with multiple people, advanced MFA options (YubiKey and fingerprint login), emergency access, dark web monitoring, and 1 GB secure cloud storage. LastPass Families adds up to 5 users, unlimited shared folders, and a family management dashboard.

Bottom Line:

LastPass has a good free plan for Firefox users — it has advanced security, includes a wide range of features, and comes with an intuitive Firefox extension. I found LastPass’s browser extension for Firefox to be very simple to understand and use, and all of the provided functionalities worked exactly as promised. While LastPass Free is really good, upgrading to LastPass Premium also gets you syncing across all devices, one-to-many password sharing, dark web monitoring, cloud storage (1 GB), and more. You can test LastPass’s premium features with a 30-day free trial.

5. RememBear — Best User-Friendly Password Manager for Firefox

5. <a href="" title="RememBear" rel="sponsored noopener norefferer" target="_blank" data-btn-name="Affiliate Link - 213345" data-btn-indexed="1">RememBear</a> — Best User-Friendly Password Manager for Firefox

RememBear is a good option for less tech-savvy users — it offers secure and intuitive password protection, integrates seamlessly with Firefox, and comes with cute bear graphics that make password management really fun!

RememBear’s Firefox extension is the easiest to use on this list — it makes password generating, saving, and auto-filling very simple, even if you’ve never used a password manager before.

RememBear doesn’t have as many advanced features as Dashlane, but it has all of the essentials, including:

  • Unlimited passwords across unlimited devices.
  • Secure cloud backup.
  • Account recovery.
  • Biometric login (on mobile).
  • One-time code generator.

RememBear has one of the simplest account recovery options around (it’s called a “Backup Kit”). Creating a Backup Kit is very simple — RememBear will provide you with a unique 25-digit code (New Device Key), and all you have to do is print this code and write your master password on the same piece of paper. If you forget your master password or lose the device where you’re logged into RememBear, you can easily gain access to your account with the information on your Backup Kit.

RememBear Free isn’t bad, but it only works on 1 device. RememBear Premium stores unlimited passwords on unlimited devices, adds multi-device sync,account recovery, and priority customer support.

Bottom Line:

RememBear is secure, intuitive, and very fun — it has an easy-to-use Firefox extension that makes generating strong passwords and auto-filling logins and forms as simple as possible. RememBear also comes with additional features like account recovery, a one-time password generator, and cute bear graphics that show you how to use RememBear’s features. While RememBear doesn’t have as many extras as some other password managers on this list, it’s a great option for non-technical or beginner users. RememBear Free includes a free trial of RememBear’s premium features.

Top Brands That Didn’t Make the Cut

  • Sticky Password. Sticky Password is an easy-to-use password manager, but it lacks a lot of the features that the other products on this list have, including dark web monitoring, emergency access, and encrypted storage. Plus, Sticky Password’s browser extension is a bit outdated and makes your data seem unorganized.
  • 1Password. 1Password is a great password manager, but 1Password’s browser extension isn’t as good as the other brands listed here. Also, 1Password only lets you share passwords with other users if you purchase the plan for families.
  • Bitwarden. Bitwarden is one of the cheapest password managers on the market, but it’s not very intuitive. During my tests, Bitwarden gave me a lot of problems, not the least of which is that it didn’t accurately fill out a lot of web forms (where all the others did).

Doesn’t Firefox have a built-in password manager?

Yes, but it’s not very good. Firefox’s built-in password manager — Lockwise — has basic functionality, but it lacks most of the features that are included in the best third-party password managers for Firefox.

Lockwise has a password generator, but it doesn’t generate very strong passwords. Lockwise also saves and auto-fills passwords, but the auto-filler doesn’t work all of the time. Not to mention that Lockwise only works on Firefox, so if you switch to another browser, you won’t have access to your Lockwise password vault.

Firefox’s built-in password manager also doesn’t let you share passwords with other users, analyze the strength of your passwords, or check whether your data was leaked on the dark web.

Third-party password managers like Dashlane have all of these features, plus Dashlane also has cloud storage, a one-click password changer, a VPN, emergency access, and lots more.

Isn’t Firefox’s built-in password manager secure enough?

Not really. Firefox’s built-in password manager uses 256-bit AES encryption and has a zero-knowledge policy, but it doesn’t have a lot of the security features I expect from a premium password manager — advanced multi-factor authentication, password auditing, or data breach monitoring (like Dashlane, LastPass, and Keeper all do).

Firefox’s built-in password manager also doesn’t require users to use master passwords to gain access to the password vault, and all user data is stored in a user’s Firefox account — this is not great security-wise.

All of the password managers on this list use master passwords along with a wide range of other security features to keep user data as safe as possible.

Are third-party password managers safe?

Yes! All of the password managers I recommend for Firefox users are extremely safe — they use AES 256-bit encryption, have zero-knowledge architecture, provide a range of two-factor authentication options, and come with additional features like password auditing, dark web monitoring, cloud storage, emergency access, and more.

Some password managers also include unique features for added security. For instance, Dashlane has a VPN with unlimited data, and Keeper has an encrypted messaging chat.

Are password managers easy to use on Firefox?

Yes! All of the password managers on this list are very easy to use, both for non-technical and advanced users.

RememBear is the best password manager for beginners — and it even includes cute bear graphics that make password management even simpler and more fun!
