TL;DR: Linux environments have remained one of the largest holdouts for phishing-resistant authentication, leaving critical infrastructure users dependent on passwords until now, according to RSA Security. The governance shift is not just convenience, because Linux access often sits inside high-value operational paths where credential compromise can have outsized blast radius.
NHIMG editorial — what this means for NHI practitioners
By the numbers:
- RSA set a goal of deploying 100% passwordless authentication for its own global workforce using its own RSA ID Plus platform.
Questions worth separating out
Q: How should security teams implement passwordless authentication for Linux users?
A: Start with Linux populations that have the highest privilege or operational impact, then align enrollment, recovery, and fallback rules with the same policy used on other platforms.
Q: Why does Linux support matter in a passwordless IAM programme?
A: Linux matters because many enterprises run infrastructure, administrative tooling, and sensitive workloads on it, yet still leave those users on weaker authentication.
Q: What breaks when passwordless excludes Linux environments?
A: Authentication policy fragments, privileged access becomes harder to govern consistently, and audit evidence no longer reflects the real estate.
Practitioner guidance
- Map Linux identities into your passwordless rollout scope Inventory every Linux user group, host class, and administrative path that still depends on passwords, OTP, or shared credentials.
- Standardise phishing-resistant login across all operating systems Apply the same assurance policy to Linux that already governs Windows, macOS, iOS, and Android.
- Redesign break-glass access before enforcement begins Create a separate emergency path for Linux access that is time-bound, logged, and reviewed after use.
Teams should measure assurance by the hardest platform, not the easiest one?

Linux passwordless is now an identity governance issue, not just a UX upgrade. The practical significance of this capability is that Linux stops being the exception that weakens enterprise authentication policy. When the same phishing-resistant methods can span Linux, Windows, macOS, iOS, and Android, teams can finally apply consistent assurance rules across the user estate. The practitioner takeaway is simple: if Linux remains password-based, passwordless is not actually enterprise-wide.
A few things that frame the scale:
- 70% of organisations grant AI systems more access than they would give a human employee performing the exact same job, according to the 2026 Infrastructure Identity Survey.
- That same survey found only 44% of organisations have implemented any policies to manage their AI agents, despite 92% agreeing that governing AI agents is critical to enterprise security.
A question worth separating out:
Q: How do you know if passwordless coverage is actually enterprise-wide?
A: Measure coverage by operating system, user role, and access path rather than by overall adoption alone. If Linux administrators, server operators, or critical application users still rely on passwords or OTP as a fallback, the programme is not truly enterprise-wide.
