Are you accessing a webpage, or manually entering a password from your keyboard elsewhere?
Some websites and services will intentionally "hide" the password characters from view as they are typed, this being an intentional measure - designed to help avoid someone else, overlooking your screen, from seeing the password.
Some websites and services have a button - adjacent to the password field - that will reveal the full password that you have typed.
