iPhone and iPad by default comes with a 4 digit passcode for unlocking when it is locked. This is called simple passcode since it is easier to remember but the flip side is simple passcodes is not secure especially when you have more private data on your phone. It is also very easy for someone to observe the password just by looking at the screen when you are typing the 4 digit numbers. At any case it is safer to have more secure alphanumeric password and here is how you can set alphanumeric password in iOS for your iPhone or iPad.
Set Alphanumeric Password in iOS for iPhone and iPad
Tap on “Settings” icon on the home screen of your iPhone or iPad and navigate to “Touch ID & Passcode”. You only see the “Passcode” option either your device is not supported for touch id or the iOS version is lesser than 8.
By default the “Simple Passcode” will be enabled allowing you to have 4 digit number as passcode. Disable this option by tapping on the slider and enter the existing 4 digit passcode when asked for.
Now you will be asked to enter the password with normal iOS keyboard which means you can enter any alphanumeric password like “Password@123”.
Enter the password and tap “Next”, then repeat the password again and tap “Done” to complete the password change. Now lock you phone by pressing the side button and then click on the “Home” button to unlock. You will be prompted to enter the alphanumeric password with the keyboard shown unlike only the number options shown with simple passcode.
