New to iOS, worried about the security of your iPhone or iPad, and wondering how to set a Passcode Lock for better protection? While the current version may not be perfect, it provides a number of real advantages over just leaving your iPhone, iPod touch, or iPad unlocked. It's also easy to set up. here's how:
To simple, 4-digit Passcode Lock:
If 4 numbers just doesn't make you feel secure enough, you can switch to a stronger, alphanumeric Passcode.
If you only enter numbers, you'll still get the numerical keypad on the Lock screen, making it easier to enter. While not as strong as an alphanumeric Passcode, a longer numeric PIN is stronger than the basic 4-number sequence.
Siri, has the ability to bypass Passcodes for some functions, like making calls or sending messages. If you consider this a security risk, you can toggle it off from the same screen.
At the bottom of the page, you have an option to Erase Data in the event of ten incorrect passcode entries.
If you have small children who think it's a fun game to tap away at the numbers while your phone turns red, you may not want to enable this or you'll be restoring your phone a lot. Security is constantly at war with convenience, make your choice.
Once you've enabled a Passcode Lock on an iPhone 4S, iPhone 4, iPhone 3GS, iPad 2, iPad, iPod touch 4, or iPod touch 3, you get the added benefit securing the hardware encryption keys. This makes everything from email to App Store apps more secure.
