Passive authentication confirms a caller’s identity in the background — from how they sound, the device they’re using, and how they behave — instead of interrogating them with questions.
Active vs. passive
Active methods ask the member to do something: answer questions, read a code, recite a passphrase. Passive methods work quietly while the conversation happens naturally, so a verified member is helped faster and a risky caller is flagged without tipping them off.
What it’s made of
Passive authentication blends several signals:
- Voice biometrics — the member’s natural voiceprint, no passphrase required.
- Device and carrier intelligence — is this call coming from a trusted source?
- Behavioral patterns and risk scoring across the full call.
Friction only when it’s needed
The goal isn’t to remove every check — it’s to apply them intelligently. With Confirm, low-risk callers sail through while higher-risk calls step up to a One-Time Passcode or additional knowledge checks. You decide the thresholds.
