By holding down the home button on your iPhone, you 鈥 and anyone else 颅鈥 can quickly access Siri even without entering a passcode. She won鈥檛 let you access any apps, but addresses and directions aren鈥檛 off limits. To make your phone more secure, go into Settings, General, Passcode Lock, and turn Siri 鈥渙ff.鈥 This keeps her completely hidden beneath the passcode lock, making it impossible for anyone without the passcode to access her wealth of information.
