    KeePass

    KeePass

    A lightweight and easy-to-use password manager

    KeePass Password Safe is a free, open source, lightweight, and easy-to-use password manager for Windows, Linux and Mac OS X, with ports for Android, iPhone/iPad and other mobile devices. With so many passwords to remember and the need to vary passwords to protect your valuable data, it’s nice to have KeePass to manage your passwords in a secure way. KeePass puts all your passwords in a highly encrypted database and locks them with one master key or a key file. As a result, you only have to remember one single master password or select the key file to unlock the whole database. And the databases are encrypted using the best and most secure encryption algorithms currently known, AES and Twofish. See our features page for details.

    Prevent Screen Saver

    Randomly move mouse one pixel to prevent screensaver from activation

    The concept of PSS is simple. Allow users to override screen saver settings and control how/when Microsoft Lync displays your status as Green. If you are an advanced desktop user or happen to work in IT, VDI’s and Terminal server connections can be quite annoying to manage when the workstations or servers keep locking. This small utility has one simple task: move the mouse one pixel every 60 seconds and can be used to assist in many different ways to make our jobs and lives just a tad bit less annoying.
