Systems and methods for verifying that an optical transceiver has access privileges to received microcode. An example environment may include an optical transceiver that is coupled to a host computing system. The optical transceiver includes a memory that has thereon an optical transceiver access identifier. The optical transceiver memory is also configured to receive microcode that includes a microcode access identifier. Whenever new microcode is received by the optical transceiver, it is verified whether the optical transceiver should have access privileges to the microcode. To verify that the optical transceiver has access privileges, the optical transceiver access identifier and the microcode access identifier are accessed. The accessed identifiers are then compared with one another. Based on the comparison, the received microcode is loaded into the memory if one or more portions of the access identifiers match.
