This article explains how to pass a One-Time Password (OTP) code generated in an Auth0 Form to the Custom Email Provider. It addresses the requirement to transfer data between the password generation widget and the email delivery service.

• Auth0 Forms
• Custom Email Provider with Actions

Form variables within flows are supported only in fields that display a + icon on the right side of the input. 

To pass a code from the Generate one-time password widget to the Send email widget when the + icon is absent, follow these steps:

1. Define a variable to hold the generated OTP code.
2. Access the generated code within the target field using the custom_vars parameter.
