The seed is different for each token, and is loaded into the corresponding RSA SecurID server (RSA Authentication Manager, formerly ACE / Server) as the tokens are purchased . On - demand tokens are also available, which provide a tokencode via email or SMS delivery, eliminating the need to provision a token to the user . </P>
