Enable passwordless login with Biometrics for users that don't have an email stored in Auth0

Feature: Passwordless login with Biometrics

Description: Currently implementation of passwordless login with Biometrics rely on user email stored in Auth0. We would like to have it enabled for cases where user PIIs are put under the deny list and thus cannot be accessed during biometric login.

Use-case: We would like to offer passwordless login with biometric for our customers. However, we have a hard-requirement of not storing user PIIs in Auth0, including email. Since biometric login relies on the email to fetch authorised devices, the flow never works and the user is always asked for password.

Hi @lleal,
