TL;DR: Account recovery remains a weak point because attackers target security questions, SMS recovery, and email-based reset flows that assume compromised accounts are not already in play, according to iProov’s Raiffeisen Bank case study. Person-centric biometric verification shifts recovery from device trust to presence and identity, making remote recovery harder to abuse.
Editorial analysis by NHI Mgmt Group, based on content published by iProov: “Why Leading Banks Choose Biometrics for Account Recovery: Lessons from Raiffeisen Bank’s Security Transformation”.
By the numbers:
- The bank said its recovery process achieved a 97-98% success rate for legitimate customers completing biometric verification.
- The revised process completes in approximately 80 seconds.
Key questions
Q: What breaks when account recovery relies on security questions and SMS codes?
A: Those methods break when an attacker already has enough context to impersonate the user or intercept the recovery channel.
Q: Why do weak recovery flows increase account takeover risk?
A: Weak recovery flows create a parallel access path that often bypasses the controls used at sign-in.
Q: How can security teams tell whether recovery controls are too weak?
A: Look for repeated resets, frequent support escalation, and recovery methods that depend on information available in public sources.
Practitioner guidance
- Redesign account recovery as a high-risk IAM journey Map every recovery step that can restore access, bind a new device, or reopen a locked account, and assign stronger assurance to those paths than to ordinary sign-in.
- Replace knowledge-based recovery with person-centric verification Remove security questions and similar static recovery checks where they remain in use, and require live person verification for remote reactivation or device transfer.
- Separate device trust from identity proofing Do not treat a trusted phone or enrolled device as proof of the rightful account holder when the recovery event creates a new trust relationship.
Bottom line: Recovery is a common blind spot because it can be easier to abuse than the primary login flow, especially when it depends on knowledge or possession factors alone.

Account recovery is a privileged access path, not a customer-service afterthought. When organizations harden primary login but leave recovery flows dependent on security questions, SMS codes, or inbox access, they create a secondary control plane that attackers can target first. The governance error is treating recovery as an operational convenience layer rather than as a high-risk identity decision point. Practitioners should classify recovery as part of the access lifecycle and govern it accordingly.
A question worth separating out:
Q: Should organisations use biometrics or help desk verification for account recovery?
A: They solve different problems. Biometrics are better when the organization needs to verify the real person remotely, while help desk verification can still play a role in escalations that require human review. The key decision is whether the recovery event creates enough fraud risk to justify live person verification before access is restored.
