KeePass Password Safe is a free, open source, cross-platform and light-weight password management utility for Microsoft Windows, with unofficial ports for Linux, Mac OS X, iOS, Android, and Windows Phone. KeePass stores all usernames, passwords, other fields, including free-form notes, in a securely encrypted database, protected by a single master password and/or key file. By default the KeePass encrypted database is not stored in the cloud but locally.
