This robust password manager is a must-use freeware tool that supports multiple operating systems and browsers. With LastPass, you create a master password, and then it uses automatic form filling and one-click log-in to simplify password entry.
LastPass will create secure passwords for you, as well as allow for secure password sharing, password import and export, secure note-taking, and password backup and restore. Because the data is stored on its encrypted servers, you can access your passwords remotely. If you're worried about key logging, LastPass can make a single-serving-use password for you. You can manually add sites, like financial ones, that would otherwise prevent the in-browser password manager from saving your password.
The interface is a basic set of fields to fill out, with several drop-down menus, but that should make it simple to use, if not outright familiar to many people.
