Reset Device

While your device is locked, you can still receive notifications of new email and text messages, make an emergency phone call, view your battery charge level, set an alarm, or take a picture.
To conserve battery power and avoid accidental key presses, lock the screen. To help to avoid unauthorized use of your device, you need to set a device password.
In your display and security settings, you can set your device to lock itself after a certain amount of inactivity. You can also write a custom message that displays on the locked screen.
If you forget your password, it can't be recovered. BlackBerry recommends that you back up your data regularly. By default, for security reasons your device data is deleted when an incorrect password is entered ten times.

Change or remove your device password

CAUTION:
If you can't remember your password, the only way to change your password or regain access to your BlackBerry device is to delete all of your data by completing a security wipe.   

1. On the home screen, swipe down from the top of the screen.
2. Tap Settings > Security and Privacy > Device Password > Change Password.

To stop using a password, set the Device Password switch to Off.


Change your work space password

1. On the home screen, swipe down from the top of the screen.
2. Tap Balance > Change Password.
3. To unlock your work space and BlackBerry device using the same password, set the Use as my device password switch to On.

Take care to remember your work space password, as it can't be reset or recovered. When you exceed the number of allowed attempts to enter your work space password, your work space and all of its contents are deleted.
