Configure the Email one-time password \(OTP\) to enable OTP-based authentication for users in your instance.

Install Now Assist for Platform `sn_genai_platform` for activating AI voice agents before Email OTP can be configured.

## Procedure

1.  Navigate to **All** > **Authentication Factors** > **Email OTP Factor** > **Email OTP Service Configuration**.

2.  Select **New**.

3.  Specify the following fields on the form:

    |Field|Description|
    |-----|-----------|
    |Service Profile Table|Select the table associated with the AI voice agent service profile. For example, `sys_now_assist_d...` \(Now Assist Deployment\).|
    |Service Profile|Select the specific AI voice agent service profile to associate with the Email OTP configuration. For example, `Voice Deployment: Example`.|
    |Table|Select the table that contains the user records. Defaults to `User [sys_user]`.|
