Want a little stronger security lock-down for your iPhone than what the 4-digit PIN offers? Weblog 9 to 5 Mac details how to enable a more secure alpha-numeric passcode on your device with a few tweaks.
You’ve always been able to turn on the passcode lock in Settings -> General, requiring users to enter a four-digit PIN to unlock your device. But if you’ve ever wanted a little added security, 9 to 5 Mac has put together a simple profile using Apple’s corporate development kit that you can install on your device to enable the alpha-numeric passcode. It’s a one-click download-and-passcode affair, but if you’d prefer not using their pre-made profile, you can make one yourself by following these instructions.
