# Authentication factor configuration for AI voice agents

To secure voice agent environments, configure authentication factors that first identify the caller, then authenticate them before granting access.

Configuration involves:

-   [User identification](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/platform-security/authentication/configuring-authentication-factors-for-ai-voice-agents.md)
-   [User authentication](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/platform-security/authentication/configuring-authentication-factors-for-ai-voice-agents.md)

## User identification

User identification forms the foundational layer of security for AI voice agents. You can configure knowledge-based authentication \(KBA\) to establish the caller identity before any authentication steps.

## User authentication

After identification, authentication confirms the caller's identity before enabling access to sensitive resources or actions. ServiceNow AI Platform supports both single-factor and multi-factor authentication \(MFA\), enabling administrators to tailor security configurations according to assurance levels and user roles. Supported factors include numeric PINs, authenticator app codes, one-time passwords over SMS and email, push notifications, and knowledge-based questions.

## General guidelines

-   Use multi-factor authentication as the default approach for stronger security.
-   Regularly review and update authentication factor configurations to address evolving threats and maintain conformance.

The following matrix shows the authentication factor combinations based on assurance level and authentication strategy.
