How do organisations know whether account protection is actually improving?

What improvement should the numbers show?

account protection is improving when the organisation can see less dependence on knowledge-based credentials and more use of phishing-resistant sign-in methods. The clearest signal is not simply “more authentication,” but a shift in the failure profile: fewer password resets, fewer SMS-based approvals, and fewer account takeovers traced to social engineering.

That means the measurement should focus on behaviour and outcomes, not just rollout activity. A programme can add controls and still remain fragile if users keep falling back to shared secrets, recovery questions, or reusable passwords.

Which signals show the takeover path is shrinking?

The practical indicators are the ones that map to the common compromise route. Rising passkey enrolment tells you whether strong authenticators are actually being adopted. Declining password and SMS use shows whether weak or interceptable factors are being displaced. Falling successful logins that start from unsolicited links or messages suggests phishing is becoming less effective, even if attackers keep trying the same playbook.

It also helps to watch the recovery path, because many account compromises succeed there after the primary login is hardened. If recovery still depends on shared secrets, static contact methods, or helpdesk-mediated exceptions, the attacker may simply move to the weakest remaining route.

How do you tell the programme is still exposed?

If recovery flows, shared secrets, and credential reuse remain common, the organisation has changed the front door but not the attack surface. In that situation, the identity programme may look better in dashboards while the same takeover path still works in practice.

Good measurement therefore compares the control mix with real user journeys. A healthy trend is when successful access increasingly depends on possession of a device-bound or phishing-resistant factor, while fallback methods become rarer, tightly governed, and measurable as exceptions rather than normal usage.

Risk and Threat Considerations

The main risk is false confidence. Teams can report progress because enrolment is rising, while attackers continue to win through recovery abuse, social engineering, or reuse of old secrets. The organisation only improves when the easiest compromise paths are actually disappearing from live traffic and support workflows.

Failure mechanism: Attackers target the residual weak path, such as password reset, SMS interception, helpdesk verification, or credential reuse, after the primary login method improves.

Impact: Account takeover remains possible even though the authentication stack appears modern, so the real reduction in exposure is much smaller than the programme reports.

Practitioner Guidance

What to verify: Track success rates by authentication path, not just adoption. A passkey programme should show not only enrolment growth, but also measurable displacement of password and SMS sign-ins, plus reduced abuse in recovery and support channels.

What to measure: Use a small set of outcome metrics, such as passkey share of successful logins, proportion of accounts still relying on passwords or SMS, volume of recovery events, and the rate of logins triggered from suspicious unsolicited prompts.

Common mistake: Treating rollout completion as proof of risk reduction. The better question is whether the weakest method is still the default method when users are under pressure, locked out, or redirected by an attacker.

Practitioner takeaway: Improving account protection is visible when strong sign-in becomes the norm and weak fallback becomes exceptional, because that is what actually reduces takeover opportunity.
