Change Your iPhone to an Alphanumeric Passcode

* This article is from our Tip of the Day newsletter. . *

Touch ID and Face ID are great iPhone security features, but if you want the best protection for your device, you need an iPhone passcode. Apple's default six-digit numeric passcode is already pretty hard to crack, but you can change your iPhone passcode to one that's even more secure. You can change your iPhone's passcode to an alphanumeric code that's six digits or longer.

Why You'll Love This Tip:

You'll be asked to confirm your new passcode, and then it will be set! Make sure that your alphanumeric passcode is something you're able to remember. The longer the passcode, the more secure it is; but, if you're going to have to enter it every time you access your iPhone without Face ID or Touch ID, you might not want to go beyond 8 to 10 characters. Remember, if you forget your iPhone passcode, you might have to enter recovery mode to access your phone. Next, you may want to go over the other options you have when you change your iPhone password.
