Simple and secure password management

Kee adds free, secure and easy to use password management features to your web browser which save you time and keep your private data more secure.

Login automatically, never forget another password, stay in control of your passwords and improve their security. Powered by the world-renowned KeePass Password Safe.

Some reasons to use Kee

One of the great benefits of Kee over similar password managers is its link to KeePass, which allows you to manage more than just website passwords. For example, you could store PIN numbers, WiFi access codes, credit card details, secret notes and even small documents. You can access your passwords on many different platforms including Mac, iOS, Windows, Android and Linux. Read full details about KeePass’ features on the official KeePass website.

Kee is OSI Certified Open Source Software

Open source software has many benefits to you, not least of which is the cost. It is rare to find any open source software which costs money and Kee is no exception – it’s completely free.

Security software benefits even more so than other types of software. As has been demonstrated many times in recent decades, public and open security systems are far less likely to be compromised than their closed source equivalents.

The core principle actually dates back over 125 years and boils down to “security through obscurity is no security at all”, i.e. if your security relies on keeping the inner workings of your application secret it is likely that your security is already broken. You can read more on this topic in the fountain of all knowledge (and its associated scientific paper references).

Other applications

Modern web browsers aren't the only apps that can be enhanced by Kee. You can find advice on how to use KeeFox (the older version of Kee) in Thunderbird and other older web browsers based on Mozilla Firefox in our community forum.
