How do I add a second parent as an administrator or, how do I add a second parent to my child's Boomerang account?

Let’s answer this in two parts: 

Boomerang App in Parent Mode:

Download Boomerang Parental Control from the Google Play Store or Apple App Store and then when you install it, select LOGIN and MANAGE FAMILY DEVICES (Parent Mode) and enroll into your account using the account email and password.  Our parent mode is free and most frequently used management options, reports, communication and location is available right from the convenience of the parent phones.

Boomerang Web Management Dashboard & Daily Reports & Alerts:

The Boomerang Web Management Dashboard and the Daily Report only has one email address that can be entered.  Both parents can share the account email and password to login into the Boomerang Web Management Dashboard to access the full configuration options (check out this video for a detailed overview of the dashboard: https://youtu.be/6shLpbyNyXI)

However, that means that the Daily Report & Alerts will only go to the primary email address.  So our recommendation is to setup automatic forwarding using gmail so that both parents get the daily report and alerts.

Here's how to setup forwarding with Gmail. Make sure to go to the web version of Gmail (not the app).

Step 1: click on the small arrow on the right side of the search bar at the top of the screen. It will open this dialog. 

Step 2: Add an email (or emails) that will receive copies of the reports.
