(Solved)Question on pink bar at top

recently i have got a pink bar at top of page that look like the debug bar, but what its got in it is this
"The administrator has made adjustments so that a password may be valid only for 30 days. days. We recommend for safety reasons that you change your password now. (Profile)"
why is this on and how do i remove it. is someone trying to make me change my passwords so they can get them? i did not set any thing to do this.
