Think your iPhone lock screen will protect your privacy? It should be -- and it can be -- but sometimes it can be giving away your secrets.

In the past couple of years, there have been numerous reports of hackers bypassing the iPhone lock screen with various trickery. And most of the time it's somehow been Siri's fault.

But even when your phone is locked, she can still let thieves or pranksters to do a lot of damage, or let people see certain information.

Having Siri or other apps accessible on the lock screen can allow anyone with your phone to send emails and text messages either in and out of your contacts list without your fingerprint or passcode.

It takes just a minute to lock down your lock screen. Here's how you do it.

1. Go to the Settings on your iPhone.

2. Go to Touch ID & Passcode.

3. Enter your passcode. (If you don't have one, you should set one!)

4. Scroll down to the Allow Access when Locked section. You can change the various options to your heart's content, but the fewer things enabled, the better.

For future-proofing, Siri should not be enabled on the lock screen. And, the changes will have immediate effect.
