A Wikipedia sign in form requesting a username and password. A password is a word or string of characters used for user authentication to prove identity or access approval to gain access to a resource (example: an access code is a type of password), which is to be kept secret from those not allowed access. The use of passwords is known to be ancient.
You see, password authentication is a knowledge-based method. It requires something the user knows, i.e., his password. If the second method of authentication is still knowledge based, say a secret question like What is your mother's maiden name, then the combination wouldn't qualify as two factor authentication. Combining two passwords, likewise does not qualify as two factor authentication.
