Implementing FIDO2 for Admins is a Tactical Move. Implementing FIDO2 for Everyone is Strategic

The one thing we have learned from implementing FIDO2 security in our customer cases, is that everyone begins their phishing-resistant authentication implementation with administrators, privileged accounts, VPN users and IT staff. This makes sense because these accounts are high value, they carry the greatest risk, and they provide the easiest environment to technically implement FIDO2. This is a tactical move that brings a good level of hygiene to any IT operation.

Yet, there is a growing realisation that limiting FIDO2 deployment to privileged users only, does not address the phishing problem. The reality is that most modern attacks do not begin with the administrator account. They begin with ordinary users. Finance teams receive invoice fraud attempts. HR staff receive malicious attachments and credential harvesting emails. Procurement and customer support teams are targeted through supplier impersonation and SaaS account compromise campaigns. Remote employees routinely interact with cloud services outside traditional network boundaries. In real life, the workforce itself has become the primary attack surface.

This is why implementing FIDO2 authentication for IT admins is a tactical move, and why going full-in with FIDO2 across the whole organisation is the strategic move that must be done to change the situation. A tactical deployment protects the most sensitive accounts. A strategic deployment changes the organisation’s overall exposure to phishing and credential theft.

From our experience on the field, which is also supported by studies, we can name five major benefits of going full-in with FIDO2 to all users:

1. Elimination of phishing-related risk

Traditional MFAs such as SMS OTP, mobile push approvals and one-time passcodes rely on shared secrets or approval workflows that attackers can easily bypass. FIDO2 is based on cryptographic authentication tied to a physical security key which is bound to a legitimate service origin. As a result, credential phishing, MFA relay attacks and account takeover attempts are no longer possible.

2. Organisational resilience

When phishing-resistant authentication is deployed across the workforce rather than only for IT administrators, the organisation reduces the number of weak entry points available to attackers. This is important because typical compromise chains rely on lateral movement after an initial user account breach. Even if the first compromised user is not privileged, attackers use that foothold to escalate access, abuse delegated permissions, or compromise SaaS environments. Enterprise-wide FIDO2 deployment interrupts that process all together.

3. Improved compliance and audit readiness

European regulations NIS2, DORA and CRA are increasing requirements around strong authentication, privileged access protection, and operational resilience. Cyber insurance providers are also becoming more demanding about MFA quality. Organisations that implement phishing-resistant authentication across their workforce are in a stronger position during audits, supplier assessments, and insurance reviews because the control is not limited to a narrow subset of accounts.

4. Improved customer and partner trust

Organisations that can demonstrate phishing-resistant authentication, modern identity controls and strong credential management practices are viewed as lower-risk suppliers and service providers. Security also influences procurement decisions in regulated industries and supply chains. In sectors concerned by NIS2 requirements, phishing-resistance is already an expected baseline.

5. Strategic alignment with Zero Trust initiatives

Passwords continue to generate operational cost, user friction, and support overhead. Legacy MFA introduces complexity due to mobile dependency, recovery workflows, and MFA fatigue. FIDO2 provides a foundation for reducing that complexity over time. Organisations that deploy it across the organisation can simplify onboarding, reduce password reset volume and build a more scalable identity architecture for cloud-first environments.

Operational deployment of FIDO2 authentication across the organisation user-base is therefore a strategic move. In our experience every organisation already understands the security value of phishing-resistance, but the larger challenge has clearly been the rolling out of FIDO2 authentication at enterprise scale. FIDO2 token enrolment workflows, logistics, credential lifecycle management and replacement handling are slowing down token adoption beyond IT admins and privileged users. The SpearID® authentication platform provides a suite of solutions that combine pre-registration, managed token enrolment and fulfilment services, and automated credential lifecycle management, that radically changes this equation.

What we see, is that organisations that currently reap the greatest benefits from FIDO2 authentication, are not the ones with the strictest admin policies, instead they are the ones that treat phishing-resistant authentication as their baseline workforce identity solution.

Protecting IT administrators is obviously critically important, but protecting the overall workforce truly changes the organisation’s security posture for good.

The SpearID® authentication platform provides the following solutions for successful FIDO2 implementation:

1. SpearID® FIDO2 tokens, smartcards and authentication devices

2. SpearID® Now for the automation of Microsoft Entra ID FIDO2 token pre-registration and mass rollout

3. SpearID® One Business for cloud passwordless SSO

4. SpearID® One Enterprise for FIDO2/passkey lifecycle management, workstation, RDP/VDI and offline authentication
