About BlackBerry ID
A BlackBerry® ID gives you convenient access to multiple BlackBerry® products, including the BlackBerry® Management Center, 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.
To log in to the BlackBerry Management Center, you must have a BlackBerry ID. You can create a BlackBerry ID from the BlackBerry Management Center login page.
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 smartphone. If you have a user name and password that you use to manage email addresses on your smartphone, that user name is separate from your BlackBerry ID.
