mine have a serial/id number on the back.  I call in and register that number 
for that login.  I have not yet tried to use the same device for 2 sites.  they 
do seem to change code at pretty much the same time.  i do not see how I could 
force the code change at paypal, with the unit in my hand, since the unit in my 
hand has no broadcast abilities.  it is only a clock of sorts that kicks out 
this unique time code every 30(?) or so sec.  the two units i currently have in 
hand seem to be sort of random between each other.
