Master networking, privacy, and security for iOS and iPadOS!

Take Control of
iOS & iPadOS Privacy and Security

Glenn Fleishman

Ensuring that your iPhone or iPad’s data remains secure and in your control and that your private data remains private isn’t a battle—if you know what boxes to check and how to configure iOS and iPadOS to your advantage. While Apple biases security and privacy in your favor, Take Control of iOS & iPadOS Privacy and Security takes you into the intricacies of Apple’s choices when it comes to networking, data sharing, and encryption.

All Take Control books are delivered in three ebook formats—PDF, EPUB, and Mobipocket (Kindle)—and can be read on nearly any device.


The book comprehensively covers networking, privacy, and security in iOS 14 and iPadOS 14, answering any question you might have across all of those areas. The book covers Wi-Fi, Bluetooth, and cellular networking; third-party password managers; tracking an iOS device; USB port blocking to prevent brute-force passcode cracking; Low Data Mode for cellular and Wi-Fi data; using the Apple Watch on a Wi-Fi network; configuring and setting up Personal Hotspot and Instant Hotspot; blocking jerks and spam; two-factor authentication with an Apple ID; using AirDrop and AirPlay; solving connection problems; and much more.

The book offers insight into what information you may unintentionally expose about yourself, and how to prevent Apple and third parties from gaining access to your details. This includes the several techniques Apple has built into Safari for iOS and iPadOS that prevent advertising and tracking companies from following your actions and connecting your browsing behavior on unrelated sites.

About Glenn Fleishman

Glenn Fleishman is a veteran technology writer who has contributed to dozens of publications across his career, including Macworld, Fast Company, and Increment. He has also written dozens of editions of books in the Take Control series. He spent 2019 and 2020 building 100 tiny type museums full of real printing artifacts—a few remain available for purchase. Glenn lives in Seattle with his wife and two children.

This book has had many lives, starting a decade ago. It was part of the Take Control series when the iPad was first released in 2010 as Take Control of iPad Networking & Security, and it then merged with the iPhone as Take Control of iOS Networking & Security. After a few updates, with a crush of other books to produce, the publishers agreed to let me release the book under my own imprint, while they offered it for sale to Take Control buyers.

Across six editions as A Practical Guide to Networking & Security, then as A Practical Guide to Networking, Privacy, & Security, and finally as Connect & Secure Your iPhone & iPad, I have continued to expand and update the title to encompass more concerns, reader feedback, and Apple and other companies’ ongoing changes.

With privacy and security foremost these days—including around COVID-19 tracing—and most of my readers part of the Take Control family already, Joe Kissell agreed to bring this book back with its sixth name into the Take Control family as Take Control of iOS & iPadOS Privacy and Security. If you purchased any previous incarnation of this title, you will be familiar with some of the contents of the book, but it’s thoroughly updated for iOS 14 and iPadOS 14. In particular, the following updates were made to reflect changes in the operating systems:

  • Wi-Fi private addresses: iOS/iPadOS by default generates a unique identifier for the Wi-Fi radio in your device for each network you join. This deters tracking your device over different networks. See “Wi-Fi Private Addresses.”
  • Apple fully blocks third-party cookies: Browser tracking for advertising, marketing, and other purposes that rely on embedding cookies from other sites is now fully blocked. See “Safari Blocks Cookies.”
  • Safari privacy report: Safari in iOS/iPadOS (and newer versions of Safari for macOS) can produce a report of all the tracking attempts blocked on a page you’re visiting. See “See a Privacy Report in Safari.”
  • Safari password warning: Safari uses a secure method to check whether a password you’re entering on a webpage has been found in any previous password breach, and warns you of that. See “Examine Security Recommendations.”
  • COVID-19 tracing: Apple and Google built a privacy-respecting framework for tracking potential novel coronavirus points of contact between people. I added a chapter to explain the intricacies of the two companies’ joint approach, and how to understand your privacy risks, in “COVID-19 Tracing Preserves Privacy.”
  • WebAuthn support with Secure Enclave: Apple has continued to expand support for a highly secure second-factor system that has broad industry adoption, called Web Authentication or WebAuthn. It’s now integrated with the Secure Enclave coprocessor in iPhones and iPads. See “A Secure Second Factor for the Web.”
  • App Store privacy: Apps will soon be required to spell out how they manage your privacy, which are explained in their App Store listings. See “Apps Disclose Much More about Data Usage.”
  • Obtain tracking permission: Starting in early 2021, apps will also have to obtain your permission to use an advertising identifier and other tracking methods. See “Users Control Advertiser ID Linkage.”
  • Location fuzziness: You no longer have to share your precise location with apps that only need an approximate location. This can reduce ad networks and other organizations’ ability to aggregate information across apps to identify and track you. See “Mediate Location Access.”
