Identity verification in financial services: what IAM teams must tune

TL;DR: Identity verification now sits at the front line of financial fraud defence, as attackers shift from systems to identities and institutions must balance document checks, biometrics, liveness, and lifecycle trust, according to 1Kosmos. The decisive issue is not adding more friction, but proving a real person is behind the identity without breaking completion rates or downstream assurance.

By the numbers:

• Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
• 90% of IT leaders say properly managing NHIs is essential for a successful zero-trust implementation.

Questions worth separating out

Q: How should financial institutions balance fraud prevention and customer completion in IDV?

A: They should treat identity verification as a three-metric problem.

Q: Why do synthetic identities and account takeover beat weak onboarding controls?

A: They succeed when institutions cannot reliably prove that a real, present human is behind the identity.

Q: When should organisations use reusable identity credentials instead of re-verifying users?

A: They should use reusable credentials when the institution can bind them to an assurance level, a transaction risk tier, and a clear policy for when step-up verification is required.

Practitioner guidance

• Align verification depth to risk tier Use lighter proofing for low-risk interactions and stronger document, biometric, and liveness checks for higher-risk onboarding or transaction paths.
• Measure the full verification funnel Track accuracy, false positives, and completion rates together so you can see whether stronger security is creating avoidable drop-off or manual workload.
• Use reusable trust where policy allows Introduce verifiable credentials and identity assurance levels so trusted users can authenticate across channels without being forced back through the same proofing journey every time.
