MULTIFACTOR AUTHENTICATION
What does multifactor authentication mean in live communications?
It means you use more than one source of identity evidence during the conversation, not relying on a single static check (like a login).
Login MFA pairs a credential with a second factor: an authenticator app, a security key, or a one-time code. Once someone is through, the check is done. A live call doesn't work that way. Risk can show up at any point during a call. That’s why Pindrop passively analyzes in the background. On a call, that can include voice, device, and call origin. In a meeting, it can include passive voice authentication, live audio and video analysis, and location risk.
That's continuous identity verification: risk reassessed as the conversation develops.

Live meeting workflow
How does Pindrop bring multifactor authentication to calls and meetings?
Authentication checks happen in real-time during the conversation, evaluating signals to determine if the participant or caller is who they say they are.

Caller authentication in contact centers
Pindrop® Passport authenticates callers from the moment a call connects, through your IVR and live agent workflows.
Participant verification in virtual meetings
Pindrop Pulse® for Meetings verifies participant identity inside Zoom, Cisco Webex, and Microsoft Teams meetings. It pairs live audio and video deepfake analysis with passive voice authentication.

Where can multifactor authentication safeguard high-stakes interactions?
Anywhere a live conversation can move money, grant access, or expose data someone else wants.

THE PRODUCTS BEHIND IT
Powered by the Pindrop Platform
Pindrop technology enables enterprise contact centers to answer three key questions in order to detect AI-powered attacks: Is this identity human? Is this identity risky? Is this identity known?

Multifactor authentication for real-time communications FAQs
It is the use of more than one identity or contextual signal during a live call or virtual meeting. Evidence can include voice, liveness, device, and location context. Based on the authentication status, organizations can decide how to apply their policies.
Login MFA verifies a user once at an access point, with a credential and a second factor. Live communication MFA reads passive and contextual evidence throughout a live conversation.
Continuous identity verification reassesses identity evidence throughout a live interaction. It tells you whether a participant is still a real human and still the right human after the conversation begins.
