QUOTE: Apple’s iOS 8 is here. If you’ve got an iPhone, you’re probably champing at the bit to download Apple’s latest and greatest OS. Or perhaps you’ve already pre-ordered an iPhone 6 or 6 Plus and are ready to party with a totally new handset. Either way, now is a great time to spruce up the security of your iOS device.

1. Wait – Don’t try to be among the first adopters and wait a few days until the dust settles
2. Shred It – Wickr’s Shredder feature to sanitize your phone before wiping it when trading in
3. Check Your Security Settings – Optimize your security settings as soon as you update to iOS 8 or get your new iPhone 6
4. Location, Location, Location – right off the bat iOS 8 asks you to enable location services before you can even play with the new OS. Go through the apps that request that data with a fine-tooth comb and deciding which really need the information
5. Medical Condition setup – iOS 8 users should set up a Medical ID. This is a virtual medical ID card that includes information like blood type, organ donor, allergies, and medical conditions.
6. Fingerprint Authentication – Be sure to enable Touch ID if you have an iPhone with a fingerprint reader, and deactivate Simple Passcodes to use a longer, more complex passphrase to unlock your device.
7. Lock Down the Lock Screen –  From the Restrictions section of the General settings, you can hide apps and even prevent apps from being installed or deleted. You can also set which apps can access your microphone, or other intimate settings, and prevent those settings from being changed.
8. Go Nuclear – A strong passcode and Find My iPhone go a long way toward keeping your phone, and its data, secure. But we can go further. Set your iPhone to automatically wipe its contents after 10 failed attempts to enter a security code.
