Of course, the four-number passcode lock is a simple and fast way to secure your phone, but even that is less than secure – as you press the numbers they light up blue, so anyone watching over your shoulder can instantly crack your device. Thankfully, though, there is a much more secure way to lock your phone to potential thieves. You can change the standard four-number passcode lock to a complex password that involves an unlimited number of letters and numbers. It might take a little longer for you to unlock your phone, but it will also ensure that, if your phone is ever stolen, it will take a lot longer, or be completely impossible, for whoever has taken it to break in and steal any of your data. Here’s how to set one up.
Step 1: Settings
To find the passcode options, open the Settings app and choose General from the list. You’ll need to scroll down to find the option you need; tap Passcode Lock when you find it.
Step 2: Too simple
By default, when you enable a passcode it will be a simple four-digit number. To make your password more secure, slide the switch next to Simple Passcode to Off.
Step 3: Enter passcodes
To progress, you’ll be asked to enter your current passcode, then you’ll be prompted to create a new, complex passcode. Confirm it by entering it again and it will be set.
Step 4: Lock it up
Now, when you next attempt to unlock your phone, you will see this style of unlock screen. Enter the new passcode and tap the OK button to open your phone up.
