2FA vs MFA and passwordless login: are controls keeping up?

TL;DR: 2FA uses two factors and MFA uses two or more, but weaker implementations and poor usability still drive workarounds that reduce security, according to Axiad. The practical lesson is that authentication design only holds when identity programs balance assurance, device trust, and user friction.

NHIMG editorial — based on content published by Axiad: 2FA vs. MFA: What’s the Difference?

Questions worth separating out

Q: How should security teams decide between 2FA and MFA?

A: Teams should compare the actual assurance of each factor combination, not just the label.

Q: Why do authentication controls fail even when they are technically stronger?

A: They fail when users experience them as too difficult and create workarounds.

Q: How can organisations introduce passwordless authentication without creating new gaps?

A: Start by replacing the weakest, most abused authentication flows first, then update enrollment, device trust, and fallback recovery together.

Practitioner guidance

  • Map factor strength to recovery paths Review whether the second factor can be replaced through email compromise, helpdesk reset, or device loss workflows.
  • Reduce friction that drives workarounds Test password and MFA policies with real users, then remove steps that predictably cause note-taking, password reuse, or unsupported shadow process.
  • Prioritise phishing-resistant options for high-risk access Use stronger authentication methods for privileged users and sensitive applications first, where the business impact of account takeover is highest.

What's in the full article

Axiad's full blog post covers the operational detail this post intentionally leaves for the source:

  • Plain-language comparison of 2FA and MFA options for different user populations
  • Discussion of passwordless authentication as an end-state for user convenience and security
  • Vendor-specific examples of how authentication orchestration can reduce login friction
  • Product positioning around deploying authentication across an organisation

Authentication strength is only real when it survives user behaviour. The article's main governance message is that control design and human workarounds are inseparable. A technically stronger factor can still weaken the environment if users respond by writing passwords down or bypassing the intended flow. For IAM teams, that means assurance should be judged by how the control behaves under pressure, not by how it reads in policy.

A few things that frame the scale:

  • 91.6% of secrets remain valid five days after the targeted organisation is notified, showing a critical gap in remediation procedures, according to Ultimate Guide to NHIs.
  • 79% of organisations have experienced secrets leaks, and 77% of these incidents resulted in tangible damage, according to Ultimate Guide to NHIs.

A question worth separating out:

Q: Who should get stronger authentication first in an identity programme?

A: Privileged users, administrators, and access paths to sensitive systems should be prioritised first because account compromise has the greatest impact there. A staged rollout lets teams prove usability, support readiness, and recovery resilience before extending the model across the wider workforce.
