Pindrop Suite / Pindrop® Passport
Authenticate in real-time.Trust in every call.
Passwords can be compromised, security questions hacked. We analyze voice, device, behavior, network, and more—empowering your agents to focus on top-notch customer experiences.


New: Enroll and authenticate more callers
Smart enrollment evaluates every call for eligibility automatically. Stronger ANI validation combines signals to validate calls that used to fall through to security questions. Together, they enroll more callers and interrupt fewer of them.

Authenticate trusted customers faster. Add friction only when risk demands it.
Pindrop® Passport helps recognize and authenticate legitimate callers naturally as they interact, reducing authentication burden for customers and agents while giving you greater confidence at high-risk moments.
Take authentication off the agent’s plate
Authenticate more trusted callers before they reach an agent, helping more routine interactions stay in the IVR and reducing time spent proving identity instead of serving customers.
Increase assurance when the stakes are highest
Strengthen authentication before sensitive actions such as money movement, password resets, and profile changes, helping agents make high-risk decisions with greater confidence.
Replace friction with passive authentication
Reduce reliance on KBAs, OTPs, and repetitive security questions. Passport helps authenticate customers naturally as they interact, creating a faster experience without weakening security controls.

Trusted in contact centers where a smooth CX is critical

To date, there have been no member complaints on the new, frictionless process. And the contact center agents seem really happy.

Security and experience aren’t opposites. Great companies know how to deliver both.

On average, 200K+ callers per month were asked for their Social Security number using the legacy authentication process. That was cut by 55% month-over-month after Pindrop.

Pindrop® Passport FAQs
Pindrop® Passport is a real-time, multifactor authentication framework that continuously analyzes call audio from connection to agent. Using background signals to evaluate trust, it reduces friction for legitimate callers and flags risky interactions.
Pindrop® Passport provides real-time, continuous authentication by layering voice analysis, Phoneprinting® technology, Toneprinting® technology, metadata, and behavior analysis, along with risk analysis.
Callers can be enrolled during normal conversations without PINs or static phrases, creating voice profiles in seconds. However, enrollment isn’t required for Pindrop® Passport to provide value; it immediately reduces friction and KBAs for unenrolled callers by leveraging ANI validation, metadata, and real-time risk analysis.
On average, it saves about 45 seconds of handle time per call1 by removing up to 4 KBA questions and verifying in the IVR.
It flags high‑risk calls during enrollment using analysis of carrier data, calling patterns, and account history. Additionally, it leverages the Pindrop Intelligence Network (PIN) and Consortium, which features known fraudster ANIs, to flag suspicious attempts in real time.
