About the BlackBerry ID
A BlackBerry® ID gives you convenient access to multiple BlackBerry products, including BlackBerry® Protect and the BlackBerry App World™ storefront. After you create a BlackBerry ID, you can use a single email address and password to log in to any BlackBerry product that supports BlackBerry ID.
You can create a BlackBerry ID from the BlackBerry Protect web site, the BlackBerry Protect application on your BlackBerry device, or BlackBerry App World.
You can use any email address for your BlackBerry ID; you do not have to use an email address that you have added to your device. If you have a user name and password that you use to manage email addresses on your device, that user name is separate from your BlackBerry ID.
