If you find that you are having difficulty entering your current iPhone passcode, or if there are other people that know your passcode and you want to disable their access to your device, then it is a good idea to change it.
Fortunately, this is something that you can accomplish directly from your iPhone in just a few simple steps.
Once you have followed our tutorial below, your iPhone will be set up with a new passcode, which you will need to enter when you unlock your device, or when you visit the Touch ID & Passcode menu.
Changing a Passcode in iOS 9
The steps in this article were performed on an iPhone 6 Plus, in iOS 9. The steps are very similar in earlier versions of iOS, however.
This tutorial will assume that you know the passcode that is currently set on your iPhone. If you want to create a new passcode because you have forgotten the old one, then this method will not work. You will need to follow the instructions on Apple’s website, in this support article, for options that are available to you if you have forgotten your passcode.
- Open the Settings menu.
- Scroll down and select the Touch ID & Passcode option. If you have an iPhone that does not have the Touch ID option, then you are just looking for the Passcode menu.
- Enter your current passcode.
- Scroll down and select the Change Passcode option.
- Enter your old passcode again.
- Tap the Passcode Options button to select the type of passcode that you want to use to unlock your device.
- Choose your preferred passcode type.
- Enter the new passcode.
- Confirm the new passcode.
- If you have a security passcode set up for iCloud, then you will be asked whether you wish to update that passcode as well. If prompted, you may also need to enter your iCloud password.
Now that you know how to create a new passcode for your iPhone in iOS 9, you can update this information if someone knows your old passcode and you don’t want them to have access to your device.
If you are concerned about people being able to access Siri when your iPhone is locked, then you might wish to disable Siri access on the lock screen.
