TL;DR: Passwordless authentication removes passwords from the login flow and reduces phishing and credential-theft exposure, while MFA still depends on a first factor and can remain vulnerable when SMS or push approvals are weak, according to WorkOS. The real decision is not which login method sounds modern, but which identity assurance model fits your legacy systems, user base, and risk tolerance.
NHIMG editorial — based on content published by WorkOS: MFA vs. Passwordless authentication
Questions worth separating out
Q: How should security teams decide between MFA and passwordless authentication?
A: Decide based on assurance requirements, user population, and platform support.
Q: Why do passwordless methods reduce phishing risk more than traditional MFA?
A: Passwordless reduces phishing risk because it removes the reusable password that attackers most often steal or replay.
Q: What do organisations get wrong when they say they have MFA everywhere?
A: They often count coverage without checking the quality of the factors.
Practitioner guidance
- Map authentication methods by assurance level Separate phishing-resistant methods such as passkeys and hardware-backed keys from weaker options like SMS or push approval.
- Inventory fallback and recovery paths Review account recovery, device replacement, and help desk reset flows with the same scrutiny you apply to primary login.
- Prioritise high-risk applications for passwordless pilots Start with applications that face the highest phishing exposure or password-reset burden, then expand once recovery governance and device support are stable.

Passwordless is not a UX upgrade, it is an assurance model change. Once passwords disappear, the attack surface shifts away from shared secrets and toward device trust, enrollment governance, and recovery design. That matters because the weakest authentication path often becomes the recovery path, not the primary login flow. Practitioners should treat passwordless adoption as an identity assurance redesign, not a front-end tweak.
A few things that frame the scale:
- The average estimated time to remediate a leaked secret is 27 days, despite 75% of organisations expressing strong confidence in their secrets management capabilities, according to The State of Secrets in AppSec.
- Only 44% of developers are reported to follow security best practices for secrets management, exposing a significant developer behaviour gap, according to GitGuardian and CyberArk.
A question worth separating out:
Q: How can teams migrate from MFA to passwordless without breaking access?
A: Move in stages. Start with applications and user groups that support modern standards, keep a controlled fallback for edge cases, and verify that recovery, device enrolment, and help desk processes are ready before expansion. The migration succeeds when assurance stays visible during the transition.
