password versus pin in application authentication

In an application authentication, it is very common to see many
applications use username/password combination for authentication
access. However, some applications use username/pin combination as
well. My question is in what scenarios we should use username/password,
and in what scenarios we should use username/pin when we design the
authentication method? My observation is that pin usually is numeric
only, but password can contain both letters and numbers.

Please advice and discuss.

Thanks,
Raymond

....it depends on what the pin is. Sometimes a pin is a keyfob etc...in this
case the pin changes everytime it is used for changed based on time. These
are very secure...especially if they are not tied to a computer (keyfob)...

A pin (Personal Identification Number) is just a short numeric password.
