Passkeys & Passwordless Authentication: Enterprise Rollout 2026

The Password Is Finally Becoming Optional

For most of enterprise IT's history, "authentication" has meant a password plus, if you were doing it right, a second factor bolted on afterwards. Passkeys change the shape of the problem instead of patching it: a public/private key pair is generated on the user's device, the private key never leaves it, and sign-in becomes a biometric or PIN unlock that proves possession of that key. There is no shared secret for an attacker to phish, replay or find in a breached database, because there is no secret to steal in the first place.

That architectural shift has now reached mainstream enterprise deployment. Industry tracking from the FIDO Alliance puts global passkey usage at roughly five billion credentials, with a majority of organisations having deployed or actively rolling out passkeys for employee sign-in, and a large majority naming full passwordless authentication as an eventual goal. This is no longer an early-adopter bet — it is the direction workforce identity is moving, and the enterprises still running password-plus-OTP as their default are the outliers now, not the cautious ones.

Why Indian BFSI Is Moving First

Adoption is not evenly spread, and India is one of the markets pulling it forward rather than following. Banks and fintech platforms are piloting FIDO2 specifically to get away from SMS-based OTP, which has become the weak link in most fraud playbooks — SIM-swap attacks, OTP-forwarding malware and social-engineering scripts all target that one shared secret in transit. A passkey sidesteps the entire category of attack, because there is no code being sent anywhere for an attacker to intercept.

There is a regulatory tailwind behind the operational one. The Digital Personal Data Protection Act, 2023 raises the cost of a breach that traces back to weak or reused credentials, which gives compliance and risk teams — not just security engineering — a reason to sponsor a passwordless programme rather than treat it as a nice-to-have identity project. Where we've written previously about building audit evidence under DPDP, phishing-resistant authentication is increasingly one of the technical controls examiners expect to see, alongside the testing evidence covered in our DPDP Act VAPT evidence guide.

What Actually Changes in Your IAM Stack

Passkeys are not a bolt-on MFA app — they sit inside the WebAuthn/FIDO2 standard that your identity provider (Entra ID, Okta, Ping, or an on-prem ADFS bridge) already speaks to some degree. Rolling them out is an identity-architecture decision as much as a security one, and three choices tend to determine whether the programme goes smoothly:

• Synced vs device-bound passkeys. Platform passkeys that sync via iCloud Keychain or Google Password Manager are convenient but cross a device boundary your security team doesn't fully control. Device-bound hardware keys (YubiKey and similar) stay the right choice for privileged accounts, admin tiers and any workflow that needs to satisfy AAL3-equivalent assurance.
• Legacy application coverage. Not every internal system speaks WebAuthn natively. Most rollouts bridge older apps through the SSO layer — the passkey authenticates the identity provider session once, and legacy apps ride on that federated session rather than needing their own WebAuthn integration.
• Recovery, not just enrolment. A lost phone or a wiped laptop shouldn't mean a locked-out employee and a helpdesk ticket that reintroduces a password as the fallback. Recovery paths need their own phishing-resistant design — a second registered passkey, a break-glass hardware key held by IT, or an in-person identity check for high-privilege accounts — decided before rollout, not improvised during the first incident.

Where Passwordless Programmes Stall

• Starting with customers instead of employees. Workforce identity is the lower-risk, higher-control environment to learn in — managed devices, a captive helpdesk, and no support-cost pressure from millions of external users hitting recovery flows at once.
• No plan for the shared-device and kiosk case. Retail floors, warehouse scanners and clinical workstations often need a shared login model that passkeys, tied to one person's device, don't naturally support. These need a deliberate exception path, not a workaround discovered mid-rollout.
• Treating it as a helpdesk rollout. Enrolment needs identity verification at the point of registration — otherwise you've built a very strong lock on a door someone can still register a new key for by phone call to the helpdesk.
• Leaving passwords active "just in case." A password that still technically works is a password that will still get phished. The security benefit only fully lands once the fallback is retired for the accounts that matter most, not left running in parallel indefinitely.

A Practical Rollout Sequence

Start with IT and security staff, who can troubleshoot their own edge cases and give you real enrolment-flow feedback before it reaches the wider workforce. Extend next to privileged and admin accounts — domain admins, finance approvers, anyone with standing access that would be a high-value target — using device-bound hardware keys rather than synced passkeys. Only after both cohorts are stable should the rollout reach the general workforce, ideally alongside a specific high-fraud population such as BFSI customer-facing or transaction-approval staff, where the OTP-replacement case is strongest. Throughout, keep the password fallback path monitored and shrinking on a schedule, not left open indefinitely as an unmanaged escape hatch — this is the same discipline we apply when hardening access control as part of a broader Zero Trust implementation.

eNeoteric's secure network and identity management engagements design FIDO2/WebAuthn rollouts end to end — identity-provider integration, hardware key provisioning for privileged accounts, legacy application bridging through SSO, and recovery flows that don't quietly reintroduce a password.
