Properly clear the last entered character

Browse Source 
When enter is pressed, passwd[len] will be set to '\0'. Pressing
backspace is supposed to remove the last entered character.

But currently, the clearing has an off-by-one, as in setting
passwd[len] to '\0' just like enter would do.

You can also verify it by imagining len=1 and that it's impossible to
clear passwd[0] by pressing backspace with the current code.
