Apple Security Best Practices: Protecting Your Data in 2025

Introduction

Apple’s devices are celebrated for their seamless integration, polished design and strong security. Yet the security landscape is always evolving. Smartphone thefts and phishing scams are on the rise—over $3 billion in losses are attributed to phone theft worldwide every year, and many victims suffer emotional distress when their devices are stolen. Even more concerning, about 1 in 3 smartphone owners in the US have experienced theft or loss, and thieves often target Apple devices because they hold valuable personal and financial informationzipdo.co.

Because of these threats, Apple continues to enhance its built‑in safeguards. Features such as two‑factor authentication (2FA), Stolen Device Protection, Security Keys, Face ID/Touch ID, data encryption, and regular software updates all work together to protect your data. This guide explains how these tools work, why they matter, and how to configure them step by step. We’ll also link to relevant guides on FrediTech and other reputable sites so you can dive deeper into related topics.

Why You Need Robust Apple Security

Phone theft and online scams are increasing

Smartphone theft has become a lucrative crime. Studies show that losses from stolen phones cost consumers billions each yearzipdo.co. Approximately 60 % of stolen phones are taken in public places, often when victims are distracted. Thieves not only resell devices but also attempt to access banking and social‑media accounts; about 75 % of stolen smartphones are used for criminal activities within dayszipdo.co.

Phishing and social engineering scams are another major threat. As TidBITS summarises from Apple’s own support documentation, “social engineering is a type of targeted attack that relies on impersonation, deception and manipulation to gain access to your personal data”tidbits.com. Scammers posing as trusted companies frequently request passwords, verification codes or credit‑card details. Recognising these attacks and knowing Apple’s policies—like never asking for your verification code—can prevent identity theft.

You store more sensitive data than ever

Apple devices have become your digital wallet, photo album and health tracker. Users often sync passwords, medical data and financial information across iCloud. FrediTech’s cloud‑storage guide notes that by 2025 roughly half of the world’s data is expected to be stored on cloud platforms—up from just 25 % in 2015—and 71 % of Americans already use cloud storage servicesfreditech.com. Without strong security, criminals could exploit this wealth of personal data.

Apple provides powerful but optional safeguards

Apple builds security into its hardware (Secure Enclave chips, Touch ID/Face ID sensors) and software (iOS, iPadOS and macOS). However, many protections—like two‑factor authentication, Stolen Device Protection and Security Keys—are optional and need to be configured. Taking a few minutes to enable these features dramatically reduces the chances of your data being compromised.

Secure Your Apple Account

Your Apple Account (formerly Apple ID) is the key to iCloud, the App Store, Apple Music and other services. It houses payment details and personal information, so securing it is critical.

Turn on two‑factor authentication (2FA)

Two‑factor authentication adds a second verification step when signing into your Apple Account. Apple explains that 2FA ensures only you can access your account, even if someone knows your password. When you sign in on a new device or web browser, you must enter both your password and a six‑digit code automatically sent to your trusted devicessupport.apple.com.

Apple makes 2FA the default for most accounts and requires it for features like Apple Paysupport.apple.com. Here’s how to enable it:

On iPhone or iPad

1. Open Settings → [your name] → Sign‑In & Security.
2. Tap “Turn On Two‑Factor Authentication.” You may need to answer security questions.
3. Add trusted phone numbers or devices that can receive verification codes.
4. Enter the code sent to your trusted device to complete setup.

On Mac

1. Open System Settings → [your name] → Sign‑In & Security.
2. Click “Turn On Two‑Factor Authentication.”
3. Follow the onscreen steps to verify your identity and add trusted devices or phone numberssupport.apple.com.

Once enabled, you’ll receive verification prompts whenever you sign in from a new device. If you don’t recognise the location shown, check that the login attempt is legitimate before allowing it. You can also request a verification code via text if no trusted device is available.

Use a strong, unique password

Apple requires that your Apple Account password have at least eight characters, include upper‑ and lower‑case letters and at least one numbersupport.apple.com. Avoid using the same password on other accounts. A password manager—such as iCloud Keychain or another trusted service—can generate and store complex passwords for you.

Never share your account or codes

Apple emphasises that you should never share your Apple Account password, verification codes or account details with anyonesupport.apple.com. Apple employees will never request these details. If you need to share purchases with family, use Family Sharing rather than sharing your account.

Keep your information up to date

Apple sends notifications whenever your account is used on a new device or your password changes. If you receive a notification you don’t recognise, someone may have accessed your account. Change your password immediately and review your trusted devices.

Consider physical security keys for high‑risk accounts

For those who want an even stronger 2FA method, Apple supports Security Keys—small FIDO‑certified devices that replace the six‑digit verification code. According to Apple, security keys are designed for people seeking extra protection against phishing or social‑engineering attackssupport.apple.com. You must maintain at least two keys and compatible software (iOS/iPadOS 16.3 or macOS Ventura 13.2 or later).

Setting up Security Keys

1. Purchase two or more FIDO‑certified security keys that match your device connectors (e.g., USB‑C, NFC). Examples include YubiKey 5C NFC and 5Ci.
2. On iPhone/iPad: Go to Settings → your name → Sign‑In & Security → Two‑Factor Authentication → Security Keys and tap Add Security Keyssupport.apple.com. Follow the onscreen instructions to register each key.
3. On Mac: Choose System Settings → your name → Sign‑In & Security → Two‑Factor Authentication and click Set Up next to Security Keys. Insert or tap your key when prompted.
4. Store your keys safely, ideally in separate locations to avoid losssupport.apple.com. If you lose all your keys and trusted devices, you could be locked out of your account.

Tip: Using Security Keys strengthens your two‑factor authentication and helps prevent your second factor from being intercepted.

Protect Your Devices from Theft

Turn on Stolen Device Protection

Introduced in iOS 17.3, Stolen Device Protection adds a layer of security when your iPhone is away from familiar locations like home or work. The feature prevents thieves who know your passcode from performing critical actions such as changing your Apple ID password or turning off Find My. Apple explains that Stolen Device Protection adds two key requirements: biometric authentication (Face ID or Touch ID) for sensitive actions and a security delay of up to an hour for certain settingssupport.apple.com.

What Stolen Device Protection does

• Biometric authentication only: When away from familiar places, you must use Face ID or Touch ID (no passcode fallback) to access saved passwords, credit cards, open locked apps or erase your devicesupport.apple.com.

• Security delay: Some changes, like updating your Apple Account password or disabling Stolen Device Protection, require an hour‑long waiting period followed by another biometric check. The delay gives you time to mark your device as lost and lock it via iCloud if it’s stolen.

How to enable Stolen Device Protection

1. Ensure prerequisites: You need two‑factor authentication, a device passcode, biometric authentication and Find My enabled.

2. Open Settings → Face ID/Touch ID & Passcode.

3. Enter your passcode.

4. Tap “Stolen Device Protection” and toggle it on.

5. Choose your preference: By default, extra security measures apply only when your device is away from familiar locations. If you want the protections to apply everywhere, select “Always” under Require Security Delay.

Note: If you restore or migrate your iPhone to a new device, Stolen Device Protection settings transfer automatically but may take a while to recognise familiar locationssupport.apple.com.

Use Find My and Activation Lock

Find My is Apple’s network for locating lost devices. When you enable Find My iPhone in Settings → Your Name → Find My, your device sends its location to iCloud. You can view your device on a map, play a sound, mark it as lost or remotely erase it from iCloud.com or another Apple device. Activation Lock automatically activates when you turn on Find My, requiring your Apple ID and password before anyone can reactivate or erase the device. This makes it harder for thieves to resell your iPhone, iPad, Mac or Apple Watch.

Set a strong device passcode and use biometrics

• Passcode: Set a six‑digit (or better yet, custom alphanumeric) passcode on your iPhone/iPad via Settings → Face ID/Touch ID & Passcode → Turn Passcode On. Avoid simple combinations like 123456.

• Face ID/Touch ID: Enable Face ID or Touch ID for quick authentication. It’s more convenient than entering a passcode and ensures only your face or fingerprint can unlock the device.

• Auto‑lock: Adjust Auto‑Lock to a short interval (e.g., 30 seconds) under Settings → Display & Brightness. This reduces the window of opportunity for thieves.

Enable “Erase data after 10 failed passcode attempts”

In Face ID/Touch ID & Passcode settings you can enable Erase Data so that the device wipes itself after 10 failed passcode attempts. This feature protects against brute‑force attacks if your device is stolen. Make sure you have iCloud Backup or local backups so you can restore your data if this occurs.

Update and Encrypt Your Devices

Keep software up to date

Software updates deliver not just new features but also critical security patches. Apple recommends updating your devices whenever software updates are availablesupport.apple.com. On iPhone, iPad or Mac, go to Settings or System Settings → General → Software Update to install the latest version. Consider enabling automatic updates so patches install overnight. On a Mac, you can also automatically install Rapid Security Responses.

Enable device encryption

• iOS/iPadOS: Apple’s mobile operating systems automatically encrypt data at rest when you set a device passcode.

• macOS: Turn on FileVault in System Settings → Privacy & Security → FileVault to encrypt the startup disk. Encryption prevents someone with physical access from reading your data without your login password.

• Backups: Use iCloud Backup or an encrypted Time Machine backup for Mac to ensure your data is protected in transit and at rest.

Use a password manager and passkeys

iCloud Keychain can store and autofill secure passwords across devices. It also supports passkeys—a modern passwordless authentication method based on cryptographic keys. Passkeys are easier to use and less vulnerable to phishing. When available, choose Sign in with Apple or passkeys instead of creating yet another password. To manage saved passwords and passkeys, open Settings → Passwords on iPhone/iPad or System Settings → Passwords on Mac.

Control Your Privacy and App Permissions

Limit location, camera and microphone access

Under Settings → Privacy & Security you’ll see which apps have access to location, photos, camera, microphone and contacts. Review these permissions and revoke any unnecessary access. For sensitive apps (e.g., banking or messaging), ensure that they only access information when the app is actively in use.

Manage tracking and analytics

• App Tracking Transparency (ATT): When an app wants to track your activity across other apps or websites, iOS asks whether to allow it. Most users should choose Ask App Not to Track.

• Analytics & Improvements: In Settings → Privacy & Security → Analytics & Improvements, disable sharing iPhone analytics with Apple to limit data collection.

• Advertising: In Settings → Privacy & Security → Apple Advertising, turn off personalised ads to reduce tracking.

Review saved passwords and security codes in Messages

With iOS 17.3 and later, one‑time verification codes received in Messages or Mail auto‑delete after use. Enable this feature in Settings → Passwords → Password Options to avoid leaving codes stored in your messages.

Use Mail privacy protection

In the Mail app settings, enable Protect Mail Activity to hide your IP address and load remote images privately. This makes it harder for marketers and scammers to track your email activity.

Avoid Social Engineering and Phishing

Apple’s support documentation warns that scammers pose as trusted companies or Apple representatives to trick you into sharing personal informationtidbits.com. Here are best practices:

• Verify senders: Legitimate emails from Apple come from addresses ending in @apple.com. Avoid clicking links in unsolicited messages; instead, sign into your Apple Account directly via appleid.apple.com or the Settings app.

• Never share verification codes: Apple employees will never ask for your 2FA codes or personal details.

• Report scams: Forward suspicious emails to reportphishing@apple.com. For SMS messages, forward them to your carrier’s spam reporting number.

• Use built‑in scam filters: Enable Silence Unknown Callers in Phone settings to block calls from numbers that are not in your contacts. Use Spam Reporting features in Messages.

Protect Your Network Connections

Use secure Wi‑Fi and VPNs

Public Wi‑Fi networks at cafes or airports can be unsafe. Avoid accessing sensitive accounts on open networks unless you use a virtual private network (VPN) to encrypt traffic. If you routinely connect to public Wi‑Fi, consider subscribing to a reputable VPN service.

At home, secure your Wi‑Fi router with a strong, unique password and WPA3 encryption if available. Update router firmware regularly, and change default administrator credentials.

Disable Bluetooth and AirDrop when not needed

Leaving Bluetooth or AirDrop on can expose your device to unwanted connections. Turn off these features in Control Center when you’re not using them. Use Contacts Only for AirDrop to prevent strangers from sending files.

Backup and Recovery Planning

Enable iCloud Backup or local backups

Regular backups ensure you can restore your data if your device is lost, stolen or erased after failed passcode attempts. On iPhone/iPad, enable iCloud Backup in Settings → [your name] → iCloud → iCloud Backup. For Mac, use Time Machine with an external drive or store files in iCloud Drive.

Add a recovery contact or recovery key

Apple allows you to designate trusted people as Recovery Contacts so they can help you regain access to your account if you forget your password. You can also create a Recovery Key, a 28‑character code that you must keep safe. These options are available under Settings → [your name] → Sign‑In & Security → Account Recovery. Note that turning on a recovery key disables traditional account recovery methods; guard it carefully.

Test your backups and recovery options

Periodically ensure that your backups are working and that you can restore from them. Sign into iCloud.com or perform a test restore on a secondary device to confirm your data is recoverable.

Additional Tips for macOS Security

While this guide focuses heavily on iPhone security, Mac computers have their own best practices:

• Update macOS and apps: Keep your Mac and installed applications current. The Ultimate Mac Productivity Guide on FrediTech emphasises that software updates bring performance improvements and critical security patchesfreditech.com.

• Manage login items: Remove unnecessary login items to reduce the attack surface and improve boot timesfreditech.com.

• Enable a login password and lock screen: Require a password immediately after sleep or screen saver begins (System Settings → Lock Screen).

• Use a standard user account for everyday tasks and reserve the administrator account for software installations.

• Turn on Firewall: Go to System Settings → Network → Firewall and switch it on to block unwanted incoming connections.

• Encrypt external drives: When formatting a Time Machine drive or USB stick in Disk Utility, choose APFS (Encrypted) or Mac OS Extended (Journaled, Encrypted).

Real‑World Example: Why Stolen Device Protection Matters

Imagine you’re traveling abroad and someone steals your iPhone from your table at a café. The thief watched you enter your passcode and quickly unlocks the device. Without Stolen Device Protection, the thief could change your Apple ID password, disable Find My, access stored passwords and reset your banking app—effectively hijacking your digital life. With Stolen Device Protection enabled, the thief would need your Face ID or Touch ID to open locked apps or view saved passwordssupport.apple.com. Even if they knew your passcode, they’d be forced to wait an hour and provide another biometric check before changing critical settingssupport.apple.com. That delay buys you precious time to log in from another device, mark your phone as lost via iCloud and protect your accounts.

Frequently Asked Questions (FAQ)

What’s the difference between two-factor authentication and Security Keys?

Two‑factor authentication uses your password plus a six‑digit verification code delivered to a trusted device or phone numbersupport.apple.com. Security Keys replace that six‑digit code with a physical FIDO‑certified key, making the second factor harder to interceptsupport.apple.com.

Does Stolen Device Protection slow down my phone?

No. Stolen Device Protection only adds extra security requirements when your iPhone is away from familiar locations. You’ll occasionally need to authenticate with Face ID or Touch ID and wait for a security delay when performing sensitive actionssupport.apple.com. Everyday tasks like taking photos or checking messages are unaffected.

What should I do if I receive a verification code I didn’t request?

Don’t share the code with anyone. Change your Apple Account password immediately and review your trusted devices/sign-ins for anything unfamiliar. Enable 2FA if it’s not already on.

Are Apple devices immune to viruses and malware?

No platform is completely immune. macOS includes Gatekeeper and XProtect; iOS apps are sandboxed. Still, malware exists—keep software updated and avoid untrusted apps or profiles.

Can I use Stolen Device Protection on iPad or Mac?

As of iOS 17.3, Stolen Device Protection is iPhone-only. iPadOS and macOS rely on safeguards like Activation Lock, passcodes, and FileVault.

How do I recover my Apple Account if I lose both security keys?

There is no recovery option if you lose all security keys and have no trusted devicesupport.apple.com. Apple designed Security Keys for high‑risk individuals who can safely manage them. For most users, 2FA without security keys provides a good balance between security and recoverability.

Conclusion

Protecting your Apple devices and data requires a combination of strong passwords, multi‑factor authentication, device encryption, regular updates and vigilance against scams. Apple offers powerful tools—two‑factor authentication, Stolen Device Protection, Security Keys, Face ID/Touch ID, Find My and Activation Lock—that drastically reduce the chances of unauthorised access.
