MFA resets are a gateway for social engineering.
When users lose access to their MFA factor (a new phone, a broken device, or a stolen security key), they call the help desk to reset it. Attackers exploit this. Vishing attacks surged 442% in 2024 (CrowdStrike 2025 Global Threat Report). The Canadian Anti-Fraud Centre reported $284 million in vishing losses in the first half of 2024 alone, with recovery rates below 3%. Attackers use real names, real credentials, and impersonation tactics to convince agents to reset MFA for accounts they don’t own. NIST has explicitly classified security questions as insufficient for identity verification. Once the factor is reset, the attacker controls the account.

Verify identity before resetting multi-factor authentication.
CallerVerify triggers a real Okta, Auth0, or Entra ID MFA push to the user’s registered device before the help desk agent resets the factor. Only the legitimate user has the registered device. Attackers don’t.
Real factors, not security questions.
CallerVerify employs Okta Verify Push, FastPass, biometrics, and security keys.
Under-10-second verification.
Reduce average handle time for help desk agents, creating frictionless interactions.
Logged inside your identity provider.
Every verification produces an audit event in Okta, Auth0, and/or Entra ID.
What changes when MFA resets are
protected.
Credibility
MFA resets only happen for verified users.
Speed
Average handle time stays under control (under-10-second verification).
Consistency
Every reset is logged with verified-identity evidence.
Works with your existing identity and support stack.
One verification layer; every channel. Support no longer happens in one place. CallerVerify brings real-time identity verification into the tools and channels your teams already use.
