TL;DR: Certificate-based authentication uses PKI certificates, hardware tokens, and a PIN to deliver phishing-resistant access for Windows, macOS, and major IAM platforms, according to Axiad. It matters because it shows how stronger authentication still depends on certificate lifecycle, device security, and credential management discipline.
NHIMG editorial — based on content published by Axiad: The Why and What of Certificate-Based Authentication
Questions worth separating out
A: Organisations should deploy certificate-based authentication with the same governance they apply to any privileged identity.
Q: Why do certificate-based logins still need access reviews?
A: Because authentication strength does not limit what an account can do after login.
Q: What breaks when certificate revocation is slow or inconsistent?
A: The main failure is that a strong credential remains trusted after the business relationship or device context has changed.
Practitioner guidance
- Map certificate lifecycle ownership Assign clear responsibility for issuance, renewal, revocation, and replacement so certificate-based access is governed like any other identity lifecycle process.
- Bind certificates to managed devices Require strong device enrollment and hardware-backed storage so certificates are not treated as portable credentials without endpoint context.
- Tie CBA to access reviews Use recurring entitlement reviews to confirm that certificate holders still need the applications and administrative paths their certificates unlock.

- Step-by-step explanation of how certificate-based authentication is configured on Windows and macOS.
- The hardware token and smartcard enrollment flow, including PIN handling and certificate presentation.
- Axiad's implementation-oriented guidance on credential management systems for certificate lifecycle operations.
- Reference material on phishing-resistant MFA implementation from CISA.

Certificate-based authentication is really a lifecycle control, not just a stronger login method. The article frames CBA as a replacement for password weakness, but the governance value is broader: certificates only reduce risk when issuance, renewal, device binding, and revocation are controlled as a single identity process. That makes CBA an IAM and lifecycle problem, not a point technology decision. Practitioners should evaluate it as part of access governance, not as an isolated MFA swap.
A few things that frame the scale:
- 79% of organisations have experienced secrets leaks, with 77% of these incidents resulting in tangible damage, according to Ultimate Guide to NHIs.
- Only 5.7% of organisations have full visibility into their service accounts, which shows how weak identity inventory still is across machine and human-adjacent access paths.
A question worth separating out:
Q: Who should own certificate governance in an IAM programme?
A: Identity teams should own policy and lifecycle rules, while infrastructure or workplace teams may operate the hardware and enrollment flow. The key is a clear control boundary: identity governance decides who can receive certificates, how long they remain valid, and when they are revoked. That prevents local convenience from overriding enterprise access policy.
