10 Best Password Manager Browser Extensions of 2026

Bitwarden is the extension we would install first in either Firefox or Chrome. The vendor's download page lists extensions for nine browsers, including Tor Browser and DuckDuckGo, and its help center has dedicated articles on using the extension in Firefox private windows and on switching off the browser's built-in password manager so the two do not compete. Day to day, opening the extension on a login page shows matching items as autofill suggestions, new logins can be saved as you sign up, and you can block autofill or autosave on specific sites. The free plan is the main reason it ranks first: unlimited passwords, unlimited devices, passkey storage and a password generator cost nothing, and Premium is $1.65 per month billed yearly. On Firefox Add-ons it has roughly 1 million daily users and a 4.6 rating, the largest Firefox audience on this list. The tradeoff is polish: menus are functional rather than refined, and TOTP codes need Premium.

Proton Pass places second because its free extension gives up very little and adds one feature that matters inside a browser: email aliases. Proton's download page lists extensions for Chrome, Safari, Firefox, Edge and Brave, and the free plan covers unlimited logins, notes and credit cards on unlimited devices, with a password generator, weak and reused password alerts and passkey support. When you sign up to a new site, the same extension can create a hide-my-email alias, and the free tier includes 10 of them. Pass Plus, $1.99 per month for the first year billed at $23.88, makes aliases unlimited and adds a 2FA authenticator, vault sharing, Dark Web Monitoring and file attachments. Firefox users rate it 4.8 of 5 across more than 3,700 reviews, the best score here. The limits are reach and renewal pricing: the plan renews at $35.88 a year, and there is no listed extension for Opera or Vivaldi.

1Password has the richest feature set here and the second-largest Chrome audience, but it costs money from day one, which drops it to third under our value weighting. The vendor publishes extensions for Chrome, Firefox, Safari, Edge and Brave, and describes the extension as the main way to use 1Password in a browser: it signs you in, generates passwords and saves logins, credit cards and notes. Native apps for macOS, Windows, Linux, iOS and Android sit behind it, so the vault follows you off the browser too. The Individual plan is $2.99 per month billed yearly during the current first-year promotion and $3.99 afterward; Families covers five people for $4.49 per month in the first year. There is no free tier, only a 14-day trial. Firefox reviewers are cooler on it than Chrome users, with a 3.8 rating from about 1,900 reviews, so Firefox-first readers may prefer Bitwarden or Proton Pass.

If every device you own runs Firefox, the built-in password manager may be enough, and it ranks fourth because it is free and needs no setup. Mozilla says Firefox stores your usernames and passwords, fills them in on your next visit and lets you choose the right account when a site has more than one login. A free Mozilla account syncs saved passwords across your devices, an import wizard pulls in passwords stored in Chrome, Edge or Safari, Firefox can generate a strong unique password for each new login, and it warns you when a saved password has appeared in a data breach. The limits show as soon as you leave Firefox. It cannot fill logins in Chrome or a work browser, and Mozilla's page does not describe secure sharing, emergency access or storage for cards and documents, which the dedicated managers above include. Treat it as a good starting point that a later move to Bitwarden or Proton Pass can import from.

NordPass has the biggest Chrome Web Store following on this list, with 9 million users, and a solid if less loved Firefox add-on. In the vendor's own listing, the extension autofills and autosaves logins, stores passkeys alongside passwords, and adds Password Health checks for weak, old and reused passwords. Paid users get a Data Breach Scanner, real-time Breach Monitoring alerts, emergency access, password sharing and 3GB of space for file attachments such as passport scans, with expiry reminders. NordPass says it encrypts vault data with XChaCha20. A free plan exists, and the US App Store lists Premium at $4.99 for a month or $34.99 for 12 months, about $2.92 per month. Firefox reviewers give it 4.0 of 5 from about 1,160 ratings, behind Bitwarden and Proton Pass. NordPass's own pricing page blocked our checks from this location, so we cite the App Store price, which can differ from web checkout promotions.

RoboForm suits people whose browser time is spent on forms as much as logins. Its extension listing describes one-click logins that open a site, fill your credentials and sign you in automatically, and the same extension manages passwords, passkeys and authenticator codes, so 2FA codes do not need a separate app. It scans the vault for weak, reused or compromised passwords and sends breach alerts for up to five email addresses. Ways to open the vault are broad: Windows Hello, Touch ID, passkeys, hardware keys such as YubiKey or a trusted phone. Sharing of single items or whole folders and emergency access round out the paid plan, which costs $2.49 per month billed $29.88 a year. Firefox users rate it 4.3 from more than 4,500 reviews. The audience is smaller than the leaders, about 600,000 on Chrome, and RoboForm's download page blocked our checks, so browser support here is based on its Chrome and Firefox store listings.

Keeper is a strong extension held back by price. The download page lists extensions for Chrome, Firefox, Safari, Edge, Opera and Brave, describing autofill of logins, passkey management and record creation from the browser. Its store listing adds TOTP capture by QR code with automatic filling at sign-in, hardware security key protection, BreachWatch dark web monitoring and One-Time Share links that expire, which work even for recipients who do not use Keeper. The vault also holds passports, driver's licenses, insurance cards and SSH keys. Keeper lists SOC 2, ISO 27001 and FedRAMP High credentials and 24/7 human support. On the US App Store, Keeper Unlimited is $42.99 per year, about $3.58 per month, with a 30-day trial and no free plan. Chrome has 2 million users; Firefox has about 67,000 daily users and a 4.2 rating. For a single user who mostly fills passwords, Bitwarden or Proton Pass deliver most of this for less.

Dashlane was built around the browser extension, and its store listing shows that focus: it follows along as you browse to save and fill passwords and personal details, fills names, addresses, emails, phone numbers and checkout fields, and stores card and bank details. It adds Dark Web Monitoring with personalized breach alerts, a one-click Password Changer for compromised or reused passwords and a Password Health Score. The vendor says more than 15 million people and 20,000 businesses use it, and its Chrome extension has 1 million users while Firefox has about 110,000 daily users and a 4.2 rating. The weak spot is cost. On the US App Store, Dashlane Premium is $64.99 per year, about $5.42 per month, more than twice Bitwarden Premium. We found no free plan on the pages we could read, and Dashlane's download page did not render for our checks, so features come from its store listing.

Enpass takes a different route: your vault lives on your device or in your own cloud account, such as iCloud, Google Drive, OneDrive, Dropbox or Box, never on Enpass's servers. Its downloads page lists browser extensions for Chrome 103 or later, Firefox 110 or later, Safari, Edge, Opera, Brave and Vivaldi, and says the extension fills logins, credit cards and identities, generates strong passwords and saves new logins so you avoid copying between the app and the browser. That design suits people who distrust vendor clouds, but it means the extension depends on the Enpass app, and setup takes longer than signing in to Bitwarden or Proton Pass. The free plan stores only 25 items, which most people outgrow quickly. Premium is $1.99 per month billed annually. Firefox users should note that the Firefox Add-ons listing is disabled by the developer, so the add-on comes from Enpass's own downloads page.

LastPass still has one of the biggest extension audiences, with 8 million Chrome users and about 387,000 daily Firefox users, but it ranks last among these ten. Its download page lists extensions for Chrome, Firefox, Edge, Opera and Safari, and notes that the Firefox build also runs in Mozilla-based browsers such as SeaMonkey and LibreWolf. Universal installers for Windows and macOS add extensions to several browsers in one pass, which helps on a shared family computer. The core job, saving passwords and logging you in automatically, works as expected. Firefox reviewers are the least satisfied of any group here, giving it 3.7 of 5 across about 8,900 ratings. The free plan is restricted to one device type, so a Firefox laptop and an Android phone cannot both use it free, and Premium is $35.99 per year on the US App Store. Bitwarden's free plan covers what most LastPass free users need.
