Here are the steps I took to create the bootable USB drive (I have a Mid-2014 MacBook Pro with Retina Display): Downloaded the latest OS X El Capitan (10.11.3) from the Mac App Store.

To create your own Mac OS X recovery USB drive, all you need is a 1GB or larger USB drive. If you have a USB drive larger than 1 GB, you can create a 1.5 GB or 2 GB partition for the recovery drive because the creation process will erase the whole USB drive and use all of the available space no matter how large it is and the drive will become. Lockdown is a two-factor authentication app that works with any online service that is compatible with Google Authenticator or 1Password 2FA.
