Features & Capabilities

MasterPassword for Firefox solves the challenge of managing multiple passwords securely. Instead of remembering numerous passwords, users create one master password that mathematically generates unique passwords for every website. This method eliminates the need to store passwords anywhere, significantly reducing the risk of hacking or theft. Unlike traditional password managers or cloud-based solutions that store passwords and are vulnerable to breaches, MasterPassword crafts site-specific passwords on the fly, ensuring superior security.

Compatible across iOS, Android, Windows, Mac, Linux, and Firefox, this extension integrates seamlessly without disrupting existing password managers. It does not import custom passwords but complements other solutions for an enhanced password management experience. Users are advised to decline Firefox's prompt to save generated passwords to maintain the highest security level. Protect your online accounts effortlessly with MasterPassword for Firefox.

No option to verify or review the initially entered master password to confirm correctness.

Recent reviews

Thank you for this add-on. Wish there's an option to review the master password first entered, whether it's correct or not. Or, if there's mismatch or mistyped.
