CAUTION: If you can't remember the password for your BlackBerry device, the only way to change your password or regain

If BlackBerry Balance technology is set up on your device, depending on the rules set by your administrator, you might not
be able to remove the password for your device.
On the home screen, swipe down from the top of the screen.
Settings > Security and Privacy > Device Password > Change Device Password.
To stop using a password, turn off the Device Password switch.
