Frame the risk in operating terms
Passwordless authentication can reduce phishing and password reuse, but the programme fails if enrolment and recovery rely on weaker proof. Begin with administrators and high-consequence workflows, inventory application support and identify legacy protocols. Include accessibility, shared-device, offline and travel requirements in the design.
Treat the subject as an operating system rather than a product setting. The accountable owner is the identity service owner with application, support and business representatives. Important decisions include which populations migrate first, which authenticators are approved, how identity is proved at enrolment, which recovery methods remain. Record assumptions, dependencies and accepted exceptions so a future reviewer can distinguish deliberate design from accidental exposure.
Engineer a controlled path
Use device-bound or hardware-backed credentials where appropriate and provide at least two controlled options for critical roles. Protect registration, device replacement and help-desk recovery with strong identity proofing. Remove old methods after verified migration rather than leaving passwords and one-time codes as a permanent bypass.
Build the control path in layers: phishing-resistant authenticators, strong enrolment proofing, controlled recovery, legacy method retirement, monitored emergency access. Apply stronger safeguards where a failure could change production, expose sensitive information or block recovery. Pilot changes with representative users and services, define rollback criteria and make emergency access narrower and more observable than ordinary administration.
Operate from evidence, not reassurance
Monitor credential registration, method changes, recovery, new devices and authentication failures. Provide clear support without allowing urgent requests to override proofing. Track applications and users that remain on weak methods, and give every exception an owner, safeguard and expiry.
Useful evidence includes method inventory, registration events, recovery records, application support tests, exception approvals. Keep collection protected from the systems being observed, test that records arrive when expected and assign a person who can act on a meaningful signal. Measures such as high-impact account coverage, weak method reduction, recovery success, exception age should lead to a decision, not merely decorate a dashboard.
Exercise failure and improve the design
Pilot realistic journeys: first registration, second device, lost authenticator, travel, offline work, inaccessible primary device and identity-platform outage. Include users with different roles and accessibility needs. Confirm that emergency access is controlled and monitored rather than improvised when the normal path fails.
Run a bounded exercise that forces the team to use real contacts, authority, evidence and recovery paths. Capture what was known, what was assumed and which action changed the outcome. Give every improvement an owner and validation method, then repeat the difficult part after the change instead of closing the work on written assurance.
What to do next.
- ✓Prioritise high-consequence identities.
- ✓Inventory application and protocol support.
- ✓Protect enrolment and device replacement.
- ✓Provide two controlled options for critical roles.
- ✓Remove weak fallback after migration.
- ✓Test loss, travel and service outage.
