TL;DR: Biometric authentication shifts identity verification toward fingerprints, facial patterns, voice, and behavioural traits, with deployment moving from local hardware to cloud, edge, and decentralized models, according to 1Kosmos. The real governance question is not whether biometrics work, but how organisations prove identity, manage consent, and avoid over-trusting a single factor.
NHIMG editorial — based on content published by 1Kosmos: biometric authentication, deployment models, and identity verification trade-offs
Questions worth separating out
Q: How should organisations govern biometric authentication in IAM programmes?
A: Organisations should govern biometric authentication as sensitive identity infrastructure, not as a simple login feature.
Q: Why do biometric systems still need fallback authentication?
A: Biometric systems still need fallback authentication because real users change over time and real environments affect capture quality.
Q: What do security teams get wrong about biometric identity?
A: Security teams often overestimate biometrics by treating them as a complete trust decision.
Practitioner guidance
- Separate enrollment from verification governance Define who can capture biometric templates, where those templates are stored, how long they are retained, and how re-enrollment is triggered when a user’s traits change or a capture is corrupted.
- Map biometric data custody end to end Document every system that touches biometric material, including devices, cloud services, and recovery workflows, so you can see where custody changes and where revocation authority actually sits.
- Build fallback authentication before rollout Provide non-biometric recovery paths for failed scans, injury, device loss, or privacy objections, and make sure those paths preserve equivalent assurance without creating an easy bypass.
What's in the full article
1Kosmos's full article covers the deployment and implementation detail this post intentionally leaves for the source:
- Practical discussion of biometric deployment models across hardware, cloud storage, edge computing, and decentralized identity.
- Examples of how facial authentication and document scanning are used in remote onboarding and account protection flows.
- Discussion of privacy, data ownership, and verifiable credential design choices that affect implementation decisions.
- Reference to certification and interoperability claims that implementation teams may want to validate in their own environment.

Biometric authentication is a human IAM control, not a standalone trust model. The article correctly frames biometrics as a way to verify a person by trait, but the governance burden remains on the surrounding identity system. Enrollment, storage, revocation, and fallback authentication still determine whether the control is defensible. Practitioners should treat biometrics as one factor in a broader assurance chain, not as an identity endpoint.
A few things that frame the scale:
- 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools, according to Ultimate Guide to NHIs.
- 71% of NHIs are not rotated within recommended time frames, increasing the risk of compromise over time.
A question worth separating out:
Q: How do cloud biometric models change identity risk?
A: Cloud biometric models shift risk from a single local device to a wider custody and access problem. The identity data may be easier to scale and share, but it also becomes more exposed to misconfiguration, over-access, and lifecycle gaps. Teams should evaluate where biometric evidence is stored and who can remove it.
