Once or twice a year, it’s important to take a stroll through your settings and make sure nothing is going on that you aren’t aware of. It only takes about ten minutes to conduct what I refer to as a “digital health checkup”, and there are a lot of things that could go awry if your settings aren’t right, so follow along with this handy guide to make sure you’re doing everything you can to protect yourself from things like data loss, security concerns, and privacy issues. While this is an outline for people who have Apple products (I don’t have enough hands on experience with Android devices to offer a comprehensive guide), many of the settings I suggest modifying are found on Android devices as well, they may just be worded slightly differently. Without further ado, open up your settings app and let’s get started.
This guide was made using iOS 13.2.3, so you’ll want to make sure you’re at least on iOS 13.0 for this guide to make the most sense to you.
Apple ID
First things first, tap the big banner with your name on it to check all your Apple ID settings. This is a really important section, because your Apple ID is what makes 90% of the things on your device work to their full potential. Under this page, there are a few things to check.
Name, Phone Numbers, Email — Here, you just want to take a quick peek and make sure that it has your correct name and contact info. If it doesn’t, update it.
Password & Security — Your Apple ID is one of the most important things I’m going to tell you about. Make sure you know your password, and make sure it’s a strong one. If you aren’t good at remembering passwords, don’t worry. Just come up with a secure one for now, and write it down so you don’t forget. We’ll come back to a better way to store your passwords in a bit.
Payment & Shipping — This tab is another quick check; just make sure the saved shipping addresses and payment info are correct.
Subscriptions — This is where you can see things that Apple charges you for on a recurring basis and cancel any subscriptions you no longer want. For example, this is where you’ll see in-app purchase subscriptions like Apple Music, as well as your iCloud storage plan.
The next three headings are all organized under the Apple ID section, so get cozy.
iCloud
While you’re still under the Apple ID section, we’ll want to look at your iCloud settings. This is without a doubt the most important page of settings you’ll need to wrangle in.
At the top, it shows a bar with your iCloud storage. iCloud storage is how a lot of data is saved on your phone, and is what enables it to magically stay in sync across your Apple devices. If your iCloud storage is low or you’re out, its extremely important to upgrade your storage plan. This can feel a little nickel and dime-y of Apple, but they’re truly providing a useful service here (besides, your phone probably cost $700+, what’s another $12-$36 per year to keep it running optimally?).
Below the iCloud storage section is a big list of apps with toggle buttons. There are a few that lead to other menus, but we’ll cover those in a minute. The rule of thumb with the toggles is that everything should be turned on. Assuming you don’t share an Apple ID with anyone, go ahead and flip every toggle to the on position; this makes sure that even if you don’t have a backup of your device, that content will still be kept safe, as well as be kept in sync across your devices. The most important ones are obviously going to be contacts, messages, calendars, iCloud Drive, and notes. It’s worth pointing out that if you don’t have an iCloud email address, turning that switch on will prompt you to create one. We’ll talk more about email later, but it’s a good idea to have an iCloud email account, so go ahead and set one up.
Photos — Of the few options that lead to menus, Photos is the first. Under this menu, you’ll want to make sure that iCloud Photo Library is turned on. This is what will save your photos if anything happens to your device, and it’s why it’s so important to make sure you haven’t run out of iCloud storage. You’ll also want to select “Optimize iPhone Storage” over “Download and Keep Originals”. This can save you a lot of storage space on your device, and you’ll still be able to see all your photos just like you always could, they just take an extra second to load the full resolution version. It’s worth enabling, especially if you don’t have a lot of extra device storage (local, on-device storage is different from iCloud storage — it’s a hardware component of your phone, and it can’t be upgraded — you can see how much local storage your iPhone or iPad has under General>iPhone Storage).
Keychain — This menu just leads to a simple toggle. Turn it on. It may have you go through a short setup process, but this is well worth the minute it takes to do so. We’ll talk more about iCloud Keychain later and how it can remember all your passwords for you.
iCloud Backup — As long as you have all the other toggles turned on, having a backup isn’t quite as important as everyone thinks, but still, having a belt and suspenders never hurts. Go ahead and turn iCloud backup on.
Find My
This is where you can control whether you’re sharing your location with your friends, update which device you share your location from, and temporarily (or permanently) disable sharing.
Family Sharing
If you want to be able to share your iTunes and App Store purchases, have a shared calendar and reminders list, all use the same iCloud storage plan, and share your location with your family, you can set up family sharing. This feature has a lot of benefits, but one drawback is that everybody’s iTunes and App Store purchases go through one person’s payment method. For more info on setting up family sharing, go here.
That’s all we need to do under the Apple ID section. All of the remaining settings you’ll want to check are found under the main settings page, so go ahead and head back there.
General
Another quick one. Under the “General” tab, check these few things.
About — Make sure your iPhone is named something like “Broc’s iPhone”, rather than the default “iPhone”. This is important so people can recognize which device belongs to you when using features like AirDrop.
Software Update — I’ve already mention software updates once, but they’re very important. If you have a pending software update, do it. Also, make sure you’ve enabled automatic updates so you don’t have to start them manually in the future; your device will take care of it for you in the middle of the night when new updates become available.
VPN, Profiles — Scroll down to the bottom of the “General” tab, and if you see a button that says “VPN” or “Profiles”, tap on it. If you don’t recognize the profile or VPN that’s been installed, remove it immediately. Scammers will sometimes try to talk people into installing these because they can provide dangerous access to everything you’re doing on your phone. If you don’t see either of these tabs at all, that just means you don’t have any to worry about.
Face ID & Passcode, Touch ID & Passcode
Make sure you’ve set up a strong passcode and are using Face ID or Touch ID. Biometric data, including your facial recognition and fingerprint scans, are ONLY stored on your device in a Secure Enclave. They’re never shared with Apple, never sent to iCloud, and never shared with your apps. They make your device much safer from theft and unauthorized access, and the features are so fast and work so well that you hardly notice they’re there.
Emergency SOS
This is a relatively new, potentially lifesaving feature that allows your phone to come to the rescue if you’re in danger. It provides a fast way to call emergency services, as well as share your location and send an SOS message to designated emergency contacts when the feature is used. Just make sure you’ve taken a minute to designate those contacts and know how to engage the feature if you ever need help. It’s easy to set up, but if you need some guidance, here ya go.
Privacy
This is the section that will take the most time, but it’s because it’s one of the most critical. For each of the sections below, when you tap on that menu, you’ll be presented with the list of your current apps that have requested access to that particular hardware element or type of data. After adjusting these settings, you’ll be more aware when apps send those white pop up boxes asking for access to your location or camera, and be able to make more informed decisions about whether to allow that access or not.
Location Services — First, you want to be using location services, but you want to be smart about it. Scroll through the apps that have requested access to your location, and decide which ones truly need that access to function. Apps can offer up to four location access options: never, ask next time, while using the app, and always. There are almost NO apps that need always on access to your location, and you should automatically be suspicious of any that request it. This comes down to your individual judgement, but almost all of my apps are set to “never”, while some are on “ask next time”. A handful of min are allowed access “while using the app”, but almost none are given “always” enabled access.
Contacts — Apps like Facebook will ask for access to your contacts so they can create networks of everyone you know. This is obviously bad, so you should almost always turn off access to your contacts for every app.
Photos — A lot of apps will abuse having permsission to your whole photo library. If they don’t need it, cut off their access.
Bluetooth — If you don’t know why an app needs bluetooth, turn it off. Bluetooth can be used to track your location even if you’ve already denied that same app access to your location.
Microphone — There are a lot of apps that ask for microphone permission, but very few actually need it to work properly. Scroll through this list and turn off everything that doesn’t have an obvious need to hear what’s happening around you when you use that app.
Camera — Same deal here: a lot of apps abuse camera privileges (Facebook just got caught doing so). If an app doesn’t absolutely NEED access to your camera to work properly, turn it off.
Advertising — Under this menu, make sure you turn on “Limit Ad Tracking”. This is a feature that Apple built to throw invasive advertisers off your trail, and make it harder for companies to spy on you and track your activity across apps. There’s no downside to enabling it, but there’s a huge upside.
Wallet & Apple Pay
I would encourage everyone to set up and use Apple Pay in stores, online, and in apps. It’s much safer than using a normal card because it requires authentication before allowing payments to be processed, and it doesn’t give merchants your real name or card number, so you would be totally protected from breaches like the one that affected millions of Target customers a few years ago. Plus, Apple Pay is a lot more convenient and the transactions process about four times faster than waiting on your chip card to sit in the payment terminal.
Passwords & Accounts
This is that bit I was promising about making it easier to keep up with your passwords. Since you’ve already turned on iCloud Keychain, this is where it becomes useful. Under the “Passwords & Accounts” menu, you can tap “Website & App Passwords” to view all the passwords you’ve saved to your iCloud Keychain.
Autofill Passwords — Make sure this is enabled, and your device will automatically fill in your sign in information on apps and websites where you’ve told it to remember your login info. You’ll never have to memorize another password, besides your Apple ID password, which is the master password that protects all of the ones in your keychain (so again, make sure it’s very secure!).
I personally use a few different email services, but I use iCloud as my main account. It’s a lot safer and more private than services like Gmail or Yahoo!: those companies read through your emails and use the content to send you targeted ads, whereas Apple will never read or share the contents of your inbox. You don’t have to switch all at once, but it’s a good idea to get away from companies like that. In any case, there is one specific setting to adjust no matter which accounts you use.
Load Remote Images — Ensure this setting is disabled. Having it turned on can allow people and companies who send you emails to know when, where, and how many times you opened their messages using a deceitful technology called “surveillance pixels”. If a sender sends you an email that includes images you DO want to load, you can enable them with one tap for that specific email, rather than having it on by default.
And thats it, your Digital Health Checkup is complete! This may have been more than ten minutes of adjustments for some folks if your device was particularly messy, but for most it’s a quick process of fine tuning that can make your device a lot safer, help it run better, and provide you with some useful features you may not have been taking advantage of. As a former Apple employee, I feel qualified to say that this is a comprehensive overview of the most important and sensitive settings your device has. If you’ve followed along with this guide, you can feel confident that you’re doing everything you can to protect yourself and your data.
