How do I reset my device password if I forget it?
Your BlackBerry Z30 device password can't be recovered or changed if you don't enter your current password correctly. For security reasons, the only way that you can reset your password without knowing your current password is to delete all of your device data. You can do this by entering an incorrect device password multiple times.
BlackBerry recommends that you regularly create and save a backup file on your computer.
