TL;DR: Passwordless authentication now extends to Linux, closing a long-standing gap that left many enterprise servers and workstations reliant on legacy credentials while other platforms used phishing-resistant FIDO-based access, according to RSA Security. The real question is whether IAM programmes can enforce consistent authentication policy across operating systems that still carry critical access.
Editorial analysis by NHI Mgmt Group, based on content published by RSA Security: “RSA Extends Passwordless Leadership to Linux at Authenticate APAC 2026”.
Key questions
A: Treat Linux as part of the core identity estate, not an exception.
A: Because attackers will use the weakest remaining path.
A: Look for platform-specific sign-in rules, recurring password exceptions, and Linux systems that still depend on legacy authentication for admin or production access.
Practitioner guidance
- Standardise passwordless policy across all operating systems Define Linux as part of the core authentication estate so passwordless coverage is not limited to modern desktop and mobile platforms.
- Remove permanent fallback to passwords Inventory every application and admin path that still allows password-based access on Linux, then time-box each exception until it is retired.
- Align Linux rollout with privileged access governance Use access review and enforcement controls to ensure high-risk Linux accounts do not become permanent exceptions to passwordless policy.
Bottom line: Linux support for passwordless authentication matters because enterprise estates still depend on Linux for servers, developer workstations, and operational systems.

Linux passwordless coverage closes an identity governance blind spot, not just an endpoint gap. The problem is that many IAM programmes have treated Linux as an exception class because the surrounding toolchain was harder to standardise. That leaves critical systems governed by legacy authentication even when policy says passwordless is the norm. The implication is that assurance now depends on platform coverage, not policy language.
A few things that frame the scale:
- eBay's passkey data shows 55-60% of passkey adoption happens on mobile, against around 20% on desktop.
A question worth separating out:
A: Yes, when Linux carries privileged or production access. Those systems are often where identity risk is highest, so leaving them behind keeps the strongest controls away from the most critical paths. Prioritising Linux closes the gap where password-based access is most costly to retain.
