All passwords can be broken, indeed. But that is not due to lack of 
complexity of the passwords. The breaking of passwords is dependent on 
the weakest link, which can be password encoding, storing, decoding, or 
even human handling of the password.

What you describe already exists. My bank gave me a custom 'keyboard'. 
They send me a challenge (number), i combine that with my 'password' 
(aka pincode) on the 'keyboard', and send them the response.

Fascinating stuff, computer security. You'll need a firm mathematical 
basis to make a career of it though.
