/*
// JSON export of TOTP keys from Authy
// based on the scripts and comments at <https://gist.github.com/gboudreau/94bb0c11a6209c82418d01a59d958c93>
// Last tested: 2019-03-19
// -----------------------------------------------------------
// Tested on: 
//   - Chrome version 72.0.3626.121 (Official Build) (64-bit)
//   - Authy version 2.6.0
// -----------------------------------------------------------
// Directions:
// 1. Start the Authy Chrome App
// 2. Unlock Authy with your password
// 3. Select all this code, and press Ctrl-C to copy the script into your clipboard.
// 4. In your Chrome browser, click on the menu dots in the top right corner, and select: More tools >> Extensions
// 5. Scroll down to the bottom of the Extensions page, and look for the Authy Chrome App (NOTE: you must use the APP, not the Extension!)
// 6. Click on the Details button. This will open up the Authy Chrome App extension page.
// 7. Under the Inspect views section, you should see two hyperlinks: background page and main.html. Click on the main.html hyperlink.
// 8. This will open up the Chrome DevTools window for main.html. There should be a Console window across the bottom 1/3 of the DevTools window.
// 9. Click your cursor in the Console window next to the ">".
// 10. Press Ctrl-V to paste the script into the Console.
// 11. Copy the JSON results (you may have a "Copy" button if the results are sufficiently long)
// 12. Back this file up, it contains all your TOTP secrets, and links to QR codes (generated via Google) you can scan
