KeePass Password Safe is a free, open source, and light-weight password management utility primarily for Microsoft Windows. It officially supports other operating systems through the use of Mono. Additionally, there are several unofficial ports for Windows Phone, Android, iOS, and BlackBerry devices. KeePass stores usernames, passwords, and other fields, including free-form notes and file attachments, in an encrypted file, protected by a master password, key file, and/or the current Windows account details. By default, the KeePass database is stored on local file system (as opposed to cloud storage).
KeePass is flexible and extensible, with many configuration options and support for plugins. It has a password generator and synchronization function, supports two-factor authentication, and has a Secure Desktop mode. It can use a two-channel auto-type obfuscation feature to offer additional protection against keyloggers. KeePass can import from over 30 other most commonly used password managers.
