How to Set Up a New Smartphone Safely, Step by Step

There’s a specific kind of chaos that hits every August: new backpacks, new shoes, and somewhere in a shopping bag, a shiny new phone still wrapped in plastic. Maybe it’s for a kid starting middle school. Maybe it’s your own upgrade after three years of a cracked screen. Either way, that first hour with a new phone sets the tone for everything that happens on it afterward.

Most people power it on, click through the setup screens as fast as possible, and start downloading apps. That’s understandable. It’s also where a lot of the easy wins get skipped. A little patience during setup saves you a lot of cleanup later.

Here’s a calm, step-by-step way to get a new phone ready, whether it’s landing in a teenager’s hands or your own.

Start with the basics before you personalize anything

Before you sign into accounts or start restoring old data, take care of the plumbing.

Update the software first. New phones often sit in a warehouse or on a shelf for a while before they reach you, so the operating system may already be out of date the moment you turn it on. Go to settings and check for updates before you do anything else. This closes known security gaps that a brand-new phone could otherwise carry right out of the box.

Set a real lock screen method. A passcode, fingerprint, or face lock isn’t optional. Skip the four-digit pattern if you can; a longer numeric passcode or biometric lock is harder to guess or shoulder-surf. This single step does more to protect the phone than almost anything else you’ll set up.

Turn on Find My Device (or Find My iPhone). If the phone is ever lost or stolen, this is what lets you locate it, lock it remotely, or wipe it. Set it up now, while you have calm access to the phone, not later in a panic.

Set up accounts carefully

Use a strong, unique password for the account tied to the phone. Your Apple ID or Google account is the master key to everything on the device: photos, contacts, app purchases, sometimes payment methods. Reusing an old password here is a bad trade for convenience.

Turn on two-factor authentication. This adds a second step, usually a code or prompt on another device, before anyone can log in from somewhere new. It’s one of the most effective things you can do to keep an account from being taken over. If you want a refresher on what account recovery looks like when something does go wrong, this guide on what to do if an email account gets hacked walks through the process, and a lot of the same logic applies to phone accounts too.

If this is a shared family plan or a child’s first phone, decide now whether the account will be a full adult account or a supervised one built for a minor. Both Apple and Google offer family setup options that let a parent manage app downloads, screen time, and content restrictions from their own device.

Review privacy settings before you add apps

Once the phone itself is secure, go through the built-in privacy settings before you start filling the home screen with apps.

  • Location services: Set to “ask every time” or “while using” rather than “always,” for most apps. Not every app needs to know where you are constantly.
  • Ad tracking: Both major platforms let you limit ad tracking across apps. Turning this down doesn’t make you invisible online, but it does cut back on how much gets pieced together about your habits behind the scenes.
  • Contacts, microphone, and camera access: Review which apps are asking for these by default and decline anything that doesn’t have an obvious reason to need it.
  • Backups: Decide where photos and data back up to, and make sure that backup account has its own strong password and two-factor authentication too. A backup is only as safe as the account protecting it.

If this phone will eventually connect to smartwatches, fitness trackers, or other wearables, it’s worth understanding what that data sharing actually involves. This piece on smartwatch and fitness tracker privacy covers what health and location data those devices tend to collect and how to keep it more contained.

Connect to WiFi thoughtfully

It’s tempting to just join whatever network is nearby, especially in a school building or a coffee shop while you’re still setting things up. Take a moment instead to connect the new phone to your home network first, and make sure that network itself is locked down.

If you haven’t checked your router’s encryption settings in a while, this guide to WiFi encryption and WPA3 is a good refresher on making sure your home network is as secure as the phone connecting to it. A new phone on an old, weakly secured network is still a weak link.

Install apps deliberately, not automatically

Resist the urge to restore every app from an old phone in one giant batch. Use the fresh start as a chance to reconsider what actually needs to be there.

Download from official app stores only, and check permissions each app requests during install. A flashlight app asking for your contacts list is a red flag, not a technicality.

If this phone will be used to send or receive money, whether that’s a teenager getting an allowance through an app or an adult managing shared expenses, take the setup seriously. This guide to payment app security covers how to use apps like Venmo or PayPal without leaving yourself exposed to common scams.

If this is a phone for a child or teen, consider whether you want location sharing set up between your devices and theirs. This guide to family location sharing apps walks through how to do that in a way that builds trust rather than just surveillance, which matters a lot for how the arrangement actually holds up over time.

For households juggling more than one device

Between phones, tablets, and laptops, most families are managing several devices with overlapping accounts and shared data. It’s worth thinking about the new phone as one piece of a bigger picture rather than an isolated setup task. This guide to multi-device security has a useful framework for keeping everything synced without duplicating your weak points across every screen in the house.

If the new phone is going to an older relative rather than a student, the setup priorities change a little; scam calls and phishing texts tend to be the bigger risk there. This guide to cybersecurity for older adults is worth reading alongside this one if that’s the situation.

Have the conversation, not just the settings

If the phone belongs to a child, the settings only do part of the job. A brief, honest conversation about what to do if a stranger reaches out, what a scam message tends to look like, and why they should come to you if something feels off does more than any parental control on its own. This guide on recognizing grooming warning signs is a good starting point for that talk, especially for a first phone.

A new phone is a clean slate. It’s worth spending the first hour making sure that slate starts off protected, rather than fixing gaps six months in. None of this makes a phone unhackable. It just means the basics are covered, so the bigger risks are the ones actually worth watching for.

A quick safety note

This article is general information, not professional security, legal, or medical advice. No single tool or setting makes anyone completely safe; security works in layers. If you are dealing with a live incident, such as active fraud, ransomware, or a child in danger, contact the appropriate professionals or authorities. For a threat to a child, report it to the NCMEC CyberTipline at report.cybertip.org and to local law enforcement.
