For organizations using Email-less Authentication for the Broadcast Mobile App, you have the option to include an additional layer of security during log in with Security Questions. These can be added from Mobile Settings.

These Security Questions are designed to allow your organization control over the questions and answers, based on custom question fields and curated integration of your attribute data.

To start setting up Security Questions, go to Settings > Mobile > Authentication. If you don't have any security questions set up, click the + Add New Security Question button to bring up the form. You can add up to 3 unique Security Questions.

Security Questions require a custom Question and an Answer. After selecting your Answer attribute, Answers are automatically pulled from your organization's attribute data. The available attributes which can be selected from include:

Click the Add button to add it to your list, and remember to click Save in the top right corner of your screen to save changes.

In order for a Security Question and Answer to be viable for selection, the Answer must meet the uniqueness rating threshold - meaning, there is enough data present to generate multiple choice questions in a secure manner.

When choosing an Answer, a data uniqueness rating will display, referring to the number of unique data fields available in the organization for this attribute. If an answer is Below the Threshold, it cannot be used.
​
Data Uniqueness Ratings:

Below the Threshold: 0-3 data uniqueness

Average: 4-9 data uniqueness

Very Strong: 10+ data uniqueness

If a selected Security Question later falls under the uniqueness threshold - we will turn Email-less authentication off and will send your Admin Team members an email notification.

When answering these questions, subscribers will be provided multiple choice options which are selected randomly from your data, accompanying their answer, or a None of the Above option.
