      The following token types were added in v2:

      ServerTokenDerivationLevel1Token = HMAC(indexKey, 2)

      ServerDerivedFromDataToken = HMAC(ServerTokenDerivationLevel1Token, value)

      Only ServerDerivedFromDataToken is really used in the v2 payloads. ServerTokenDerivationLevel1Token is just an intermediate type used for deriving the ServerDerivedFromDataToken.
