Passwords are one of the most common ways of authenticating a user; they are also the authentication factor that is most likely to be inserted incorrectly, maybe because they use higher and lower-case characteristics, numbers, and special characters not seen in programming. Some people may have the caps lock reversed without knowing it. When the password is inserted, it is shown as a row of dots therefore users cannot see their input, however, in the password box in Windows 10 you can press the eye to see the password that you have inserted. This reduces the risk of people being locked out.
