What are the data archival policies for old credentials? Data archival policies for old credentials define retention periods and storage methods for expired or inactive digital IDs. Policies may require secure, encrypted archiving in cold storage (e.g., offline databases) after a set period (e.g., 7 years for compliance). Blockchain-based credentials might retain immutable audit trails while moving sensitive data to private archives. Automated systems purge credentials beyond retention limits, reducing storage costs. These policies balance regulatory compliance, security, and operational efficiency, ensuring historical data remains accessible but protected.
