TL;DR: Phishing, ransomware, and weak credentials remain the dominant failure modes in identity security, and Yubico’s interview argues that password-era authentication and legacy MFA no longer match the threat environment. The editorial takeaway is that phishing-resistant hardware-bound authentication, paired with lifecycle discipline, is now a baseline control for human IAM and adjacent NHI governance.
Editorial analysis by NHI Mgmt Group, based on content published by Yubico: “Securing the skies with YubiKeys: Insights on cyber resilience in the aviation industry and beyond”.
Key questions
Q: Why does relying on passwords and legacy MFA increase legal and financial risk for security teams?
A: Passwords and legacy MFA are easier to phish, replay, or bypass, which makes identity compromise more likely.
Q: Why do phishing-resistant MFA and lifecycle management need to be implemented together?
A: Phishing-resistant MFA reduces the chance that an attacker can steal or replay a login factor, but lifecycle management determines whether the resulting account or privilege still exists when it should not.
Q: What are the signs that identity lifecycle controls are too slow?
A: Warning signs include delayed offboarding, long-lived admin access after role changes, stale authenticators on dormant accounts, and support processes that re-enable access without revalidation.
Practitioner guidance
- Adopt phishing-resistant MFA for high-value access Prioritise hardware-bound passkeys or security keys for administrators, developers, and any user path that can reach sensitive systems or data.
- Align joiner-mover-leaver events to authentication state Ensure provisioning, role changes, and offboarding remove or reissue access at the same time that employment, contract, or service ownership changes.
- Move signing and SSH keys onto managed hardware tokens Store commit-signing keys, SSH credentials, and other high-trust secrets on hardware tokens where private material never leaves the device.
Bottom line: Phishing-resistant authentication has moved from best practice to baseline because legacy MFA still leaves room for proxying and stolen credential reuse.

Phishing-resistant authentication is now a baseline identity control, not an advanced add-on: Passwords and legacy MFA still assume the defender can trust a factor that attackers routinely proxy, steal, or replay. That assumption no longer holds in high-friction environments where phishing and credential theft are operationally industrialised. The implication is that identity programmes should stop treating hardware-backed proof as a premium option and start treating it as the default for high-value access.
A question worth separating out:
Q: How should security teams use hardware keys for both login and code signing?
A: Use the same hardware-backed trust model for interactive authentication, SSH access, and code signing where assurance and provenance matter. That reduces the number of places where private keys can be copied, and it makes it easier to prove who authorised a sensitive action. The key decision is to control custody, not just the login step.
