Almost all the reviewers sound like employees who work in areas like healthcare and are fed up with having to log in again after leaving a PC unattended for a short time. To me this screams that something is fundamentally flawed with workstation authentication in the service industry. I feel that well implemented hardware 2FA a la Yubikey could be the solution here.

I do know people who use mouse movers because their employers judge their efficacy on business hour observance rather than productivity.

Not to say I enjoy retyping a complex 15-character password for having answered a phone call or refilled my mug.
