Firefox Password Manager review

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.

Who it is for

People who use only Firefox, on desktop and phone, and want nothing extra to install.

Price

Free, built into Firefox; sync needs a free Mozilla account.

With a free Mozilla account you can securely sync your passwords across all your devices.
