TL;DR: The decisive factor in enterprise passwordless rollout is architectural fit, with Secfense reporting that passkeys and FIDO2 fail or succeed based on where authentication is enforced. That pushes IAM teams to treat migration as a programme choice, not a feature toggle.
Editorial analysis by NHI Mgmt Group, based on content published by Secfense: “Passwordless in Practice: Comparing Enterprise Deployment Architectures”.
Key questions
Q: How should teams choose between native WebAuthn and reverse proxy enforcement?
A: Choose native WebAuthn when the application can verify origin-bound public-key credentials directly, because the relying party, user, and device authenticate without an extra interception layer.
Q: Why do LDAP proxy models often remain transitional?
A: LDAP proxy models often remain transitional because they preserve legacy directory authentication while a proxy translates or forwards binds to an upstream system.
Q: How do passkeys work for enterprise sign-in?
A: Passkeys use public-key cryptography, with a private key kept on the user’s device or in a synced credential store and a public key registered to the service.
Practitioner guidance
- Map passwordless enforcement layers Classify applications by where passwordless can be enforced: application code, identity layer, or front-door infrastructure.
- Separate greenfield and legacy rollout paths Allow new applications to use native WebAuthn where ownership and release cycles support it, while routing legacy or vendor-managed applications toward architectures that avoid code changes.
- Define the ownership model for agents and proxies Assign explicit operational ownership for any agent-based or reverse proxy control so maintenance, upgrades, and recovery do not become ambiguous after deployment.
Bottom line: Enterprise passwordless success depends on integration architecture more than on the choice of passkey or FIDO2 credential.

Passwordless is an architectural control, not an authentication feature. The article's core lesson is that the method matters less than where it is inserted into the enterprise stack. When application ownership is fragmented and legacy systems still dominate, the deployment model becomes the real security decision. Practitioners should evaluate passwordless as a programme design choice, not as a sign-in upgrade.
A few things that frame the scale:
- eBay's passkey data shows 55-60% of passkey adoption happens on mobile, against around 20% on desktop.
A question worth separating out:
Q: What should auditors review in passwordless rollouts?
A: Auditors should review where authentication is enforced, how passwordless methods are bound to the user and device, and whether recovery, fallback, and enrolment paths still allow password use. They should also check privileged accounts, session reauthentication, logging, and revocation controls, because weak fallback routes can undermine an otherwise strong rollout.
