Set a device password
If you forget your BlackBerry® device password, it can't be recovered. You can reset your password without knowing your current password by deleting all your device data.
Research In Motion recommends that you regularly create and save a backup file on your computer, especially before you update any software. Maintaining an up-to-date backup file on your computer might allow you to recover device data if your device is lost, stolen, or corrupted by an unforeseen issue.
