The real compliance challenge is not replacing the front-end authentication prompt but inventorying every internal system, API integration, and third-party service that uses NRIC as an authentication factor. Legacy applications typically have NRIC dependencies buried in code that hasn't been maintained or documented, and most organizations will find more of them than they expect when they start. The Bizfile portal incident that triggered this policy demonstrates the broader systemic problem: NRIC numbers were treated as authentication secrets while simultaneously being publicly disclosed, which means any legacy system still using them as a password is now working from a compromised baseline.
