Would you like freeradius act as a token? 
The principle of operation of OTP is to not store nothing, it just returns a
temporary password based an some one-way algorithm, this temporary password
is basically the result of PIN received from user.

Look at this project, maybe it can help you. It´s works jointly with radius.
