 However, user in bright environment will be easy to notice people around, but not in dark environment.

 Thus, there is security risk while user typing the username/password in dark environment, and other people may have chance to peek easier with the user’s fingers typing on the keyboard with backlight, and without noticing people around his/her

 While user typing passwords, the computer shows "*" or "●" on the display, but backlight keyboard doesn’t have any design to protect from the risk.
