LessPass is a safe and secure password manager for everyone. The tool is free and open-source, which adds to its appeal. It doesn’t follow the traditional route of password manager apps that store your passwords in cloud storage. Instead, it uses a mathematical algorithm to calculate your password each time you need it. To do that, it only needs the website you are trying to access, your login details, and your unique master password.
Since it doesn’t actually store your passwords, you don’t need to sync your account across devices. The actual calculation happens offline, locally on the device you’re using, so your private information never leaves your device. You can check the source code on GitHub, as the app is open-source.
You can use the web app version of LessPass, as well as its browser extension, or iOS or Android mobile app.
What Are the Key Features of LessPass?
LessPass is a free and open-source password keeper that doesn’t actually keep your passwords, removing the need to sync your account across devices. It works by calculating the needed password through a mathematical algorithm, giving you the password you’re looking for each time. To do so, it needs to know the website you’re trying to access, your login or registered email, and your unique master password.
With LessPass, you don’t run the risk of exposing your passwords and personal information to third parties. There is no vault or cloud storage where all of your passwords are stored, which makes LessPass one of the most secure solutions. For that reason, it can also work completely offline. All the computations happen locally on the device you’re using, and nothing ever leaves your device. Your master password is protected by PBKDF2 hashing.
Your passwords can be adjusted with the help of criteria such as length, lowercase and uppercase letters, numbers, and special characters. Because the platform is open-source, you can find the code online.
Use LessPass through its official web application or browser extension for modern browsers like Google Chrome. You can also download the mobile app on iOS and Android devices.
Is LessPass Free to Use?
Yes, LessPass is a free tool. You don’t need to pay anything to download and use it.
Which Platforms Support LessPass?
LessPass can be accessed through its web app using any modern browser. You can also install the browser extension for Chrome, Firefox, and other modern browsers on Windows, macOS, and Linux computers.
If you prefer to manage your passwords on your phone, you can download the Android or iOS mobile app.
