Beyond Passwords: The Hidden Risks and Rewards of Going Passwordless Under ISO 27001

Picture this: your company’s digital security still runs on clunky, gas-guzzling passwords, coughing and sputtering along. But the world is speeding ahead in electric silence, powered by passkeys. The promise? Fewer breaches, less friction, and a smoother ride through compliance audits. But what’s really under the hood of this passwordless revolution - and does it deliver the security boost it advertises, especially for organizations bound by ISO 27001?

For decades, passwords have been the brittle backbone of digital authentication. But with nearly half of breaches traced to password compromise, their time is up. Enter passkeys: cryptographic credentials stored securely on your device, immune to phishing and brute force, and verified using standards like FIDO2 and WebAuthn. The tech giants are all in - Google boasts 800 million passkey-enabled accounts, while Amazon and Sony are rolling out millions more.

But for organizations certified under ISO/IEC 27001 - the global gold standard for information security - switching to passkeys isn’t just a technical upgrade. It’s a compliance minefield. Annex A controls (notably 5.15, 5.17, and 8.5) demand airtight documentation, risk assessments, and robust fallback procedures. Every step, from registration flows to recovery protocols, must be mapped, monitored, and ready for auditor scrutiny.

Technically, passkeys shine. Device-bound keys offer the highest security for privileged accounts; syncable keys - spread across your devices via encrypted clouds - balance convenience and resilience. But every innovation brings new risks. Lose your device and your passkey, and account recovery becomes a thorny problem - reintroducing old threats like email compromise or social engineering. Meanwhile, attackers adapt: downgrade attacks and OAuth phishing can sidestep passkey protections if implementation is sloppy.

The transition isn’t instant. Most enterprises must juggle mixed environments, supporting both passwords and passkeys. This creates blind spots: inconsistent access controls, confused users, and complex audit trails. The burden on help desks drops - Gartner estimates password resets eat up 20–40% of support calls - but the initial rollout requires careful planning, staff training, and ironclad documentation.

Still, the benefits are real. Passkeys eliminate whole classes of attacks, speed up sign-ins, and simplify compliance across multiple frameworks (NIST, PCI DSS, GDPR, SOC 2). For ISO 27001 shops, the key is a risk-based approach: start with your most sensitive accounts, layer defenses, document everything, and keep fallback options tight and tested.

As the password era sputters out, passkeys look set to become the new gold standard. But the journey isn’t just about shiny new tech - it’s about building trust, accountability, and resilience into every login. For those racing ahead, the challenge is clear: drive the future, but never take your hands off the compliance wheel.

• Passkey: A passkey is a digital credential using cryptographic keys, stored on your device, to securely verify your identity without traditional passwords.
• FIDO2: FIDO2 is an open standard for passwordless authentication, enabling secure logins with biometrics or security keys, reducing phishing and credential theft risks.
• ISO/IEC 27001: ISO/IEC 27001 is a global standard for managing information security, guiding organizations to protect data and manage risks through an ISMS framework.
• Authenticator Assurance Level (AAL): Authenticator Assurance Level (AAL) rates how strong an authentication method is, with AAL2 and AAL3 offering higher security per NIST standards.
• Downgrade Attack: A downgrade attack tricks systems into using less secure protocols or authentication, making it easier for attackers to exploit known vulnerabilities.
