Most people carry a lot of sensitive data on their devices. If somebody steals your device, not only will your personal data be lost, but also you may seriously suffer from the consequences. You may want to have added security measurements for your iOS devices. This is also important if you are sharing your device with other people; you may not want other people easily access your personal data. You can increase the security of your device (iPad, iPod and iPhone) to ensure the protection of your personal information. Here is how:
1-Set up a Passcode Lock
You can configure a passcode for an iPad, iPod or iPhone by simply tapping Settings > General > Passcode Lock. You may configure a 4 digit password or a longer passcode with numbers and letters. You may also want to turn the Erase Data option on. This option will delete everything after 10 failed attempts.
2-Turn on and configure Location Services
Location services allow applications to determine your approximate location. Make sure that you turn on Find My iPad. Then you will want to configure Find My iPhone (or Find my iPod, Find My iPad) so that you can locate your device when you lost or when it was stolen. Please see this article regarding how to configure Find My iPhone.
You can enable restrictions to prevent access to specific features (this article explains restrictions in more details). You can restrict access to YouTube, Safari, Camera, FaceTime, iTunes, along with the installation or deletion of apps.
You can also allow or disallow Location and Accounts changes. If you want maximum protection, set Location and Accounts to “Don’t Allow Changes.” This will lock your current settings as you configured in step 2.
4-Do not use the built-in Mail app
The built-in Mail app works great, but there is no easy way to sign out and anybody using your iPad/iPhone/iPod can check/send easily emails via your email account. Instead of using the built-in mail app, get separate mail app from the App Store. For instance, if you are using Gmail as your email service, just download Gmail app and use this. Gmail app allows you to sign out and next time you want to check emails, it asks username and passwords. This way nobody but you can check your emails even if you share your device with somebody.
