The lock screen is what you see once you wake a device up. It tells you to slide from left to right to unlock your device, followed by an optional passcode prompt. Several methods of bypassing the passcode prompt have surfaced multiple times in its lifetime.

The passcode can also be brute-forced if the device is jailbroken, and the passcode is simple (four digits).[1]
