Methods and systems for implementing DevID enrollment for hardware redundant Trust Platform Modules (TPMs), are described. A system can include hardware redundancy for management modules, and for TPMs that correspond to each management module. Accordingly, a product can have a dual-TPM configuration, where both modules are associated with the same product. Further, a process that particularly considers the presence of dual-TPMs for creating, issuing, and enrolling DevID certificates is described. The process issues and maintains DevID certificates for each TPM by synchronizing dual sessions that correspond to each TPM. Also, the process accounts for duplicate identification data, for example allowing the certificate authority (CA) to sign certificates for dual-TPMs linked to the same chassis number. The process can include performing validation checks, rendezvous points, and locks to ensure that DevID certificates are successfully issued for each of the dual-TPMs, respectively.
