Multi-factor Authentication
Multi-factor Authentication (MFA) verifies identity using more than one signal to reduce fraud while preserving fast, natural experiences—especially in voice and contact center interactions. With IllumaSHIELD™, MFA is adaptive: low-risk interactions stay frictionless, while higher-risk situations automatically trigger additional verification.
What Is Multi-factor Authentication?
Multi-factor authentication confirms identity by combining two or more verification factors, such as:
- Something you are: voice biometrics
- Something you have: a trusted phone number or a one-time passcode (OTP)
This layered approach prevents impersonation, social engineering, and account takeover without forcing every user through the same steps.
How IllumaSHIELD™ Delivers Adaptive MFA
IllumaSHIELD™ embeds MFA directly into voice interactions, using real-time risk signals to decide when and how much authentication is needed.
TrustedNumber™
What it is:
TrustedNumber™ combines voice biometrics with trusted phone number intelligence to adapt verification confidence automatically.
Why it matters:
When the caller’s voice and phone number align with known, trusted patterns, authentication can proceed with minimal friction—saving time for agents and callers.
Key benefits:
- Adaptive verification confidence
- Faster authentication for recognized callers
- Reduced unnecessary step-up challenges
- Stronger protection against impersonation
One-Time Passcode (OTP)
What it is:
A secure step-up authentication factor delivered via phone or email.
When it’s used:
OTP is triggered only when risk increases or policy requires additional confirmation—rather than for every interaction.
Key benefits:
- Flexible delivery (phone or email)
- Layered security for higher-risk scenarios
- Consistent, policy-driven verification
How Adaptive MFA Works
(Step-by-Step)
Caller speaks naturally → voice biometrics are analyzed in real time
Phone number is evaluated → TrustedNumber™ increases or lowers confidence
Risk is assessed → system determines required verification level
OTP applied if needed → step-up verification confirms identity
Interaction proceeds securely → minimal friction, maximum protection
Why Adaptive MFA Is Better Than Traditional MFA
- Eliminates overuse of static security questions
- Reduces average authentication time
- Improves customer satisfaction and agent efficiency
- Scales security without adding operational complexity
Is MFA required for every call?
No. IllumaSHIELD™ applies MFA dynamically based on confidence and risk.
Can OTP be used without voice biometrics?
Illuma only offers OTP as a step-up factor alongside voice verification.
Does MFA slow down callers?
Not for trusted, low-risk interactions. Most callers experience faster authentication.
