Keeping your personal data safe from prying eyes is crucial. Our experts share simple yet effective ways to secure your device in just a few minutes.

Why Device Security Matters

For most of us, our smartphones are an essential part of everyday life. They help us stay connected, manage payments on the go, and store sensitive information. That’s why it’s vital to take steps to protect your device from security threats.


Fortunately, enhancing your phone’s security doesn’t have to be time-consuming. A few quick adjustments to your settings can make a world of difference.


Below, we’ve outlined essential updates and security measures, including phone-tracking tools. If you're using an Android device, note that the exact steps may differ depending on the brand—check the manufacturer’s website for specific instructions.



1. Keep Your Software Up to Date

Before taking any other security steps, ensure your phone is running the latest security updates. Updates patch vulnerabilities that hackers could exploit to steal your data, including passwords.


How to check for updates:

  • iPhone: Go to Settings > General > About to check your iOS version. To update, go to Settings > General > Software Update. Note that iPhone XR and newer models continue receiving updates, while older models do not.


  • Android: Open Settings and look for About phone (or a similar option). Check your Android version—devices running Android 10 or earlier are no longer supported. Updates can usually be found under Settings > System > Software Updates.



2. Enable Face or Fingerprint Unlock

While it’s possible to set up a new smartphone without any security locks, this leaves your data at risk. Without security measures, anyone with access to your phone can open apps, make calls, and transfer files.


How to enable biometric security:

  • iPhone: Go to Settings > Face ID & Passcode (or Touch ID & Passcode if your device has a Home button) and follow the setup process.


  • Android: Navigate to Settings > Security & Privacy > Device Unlock and select Face or Fingerprint Unlock.


Be cautious when using face unlock on certain Android devices—tests have shown that some models, including the Samsung S24 and S24+, can be fooled by a photograph.



3. Activate Two-Factor Authentication (2FA)

Two-factor authentication (2FA) is a quick but powerful way to add an extra layer of security to your online accounts.


Whenever you attempt to log in from a new device—such as accessing Gmail or Outlook—you’ll receive a time-sensitive code via text or an authentication app. This extra step prevents hackers from gaining access, even if they have your password.


To enable 2FA:

  • Open the app or website you want to secure.

  • Navigate to the security settings.

  • Enter your mobile number to receive a verification code and follow the on-screen instructions to enable 2FA.



4. Set Up a 'Find My' Tracking Service

Both iOS and Android come with built-in tracking tools that help you locate your phone if it’s lost or stolen. Activating this feature allows you to track, lock, or erase your device remotely, preventing unauthorised access to your data.


How to enable tracking:

  • iPhone: Go to Settings > [Your Name] > Find My > Find My iPhone and turn it on. You can access it via iCloud.


  • Android: Navigate to Settings > Security (or Google > Security). Search for Find My Device and enable it. Location services should also be turned on under Settings > Location. You can track your phone at Android’s Find My Device.


  • Samsung devices: Use SmartThings Find via Settings > Samsung Account > Find My Mobile or visit SmartThings Find.



5. Use Strong, Unique Passwords

A strong password is your first line of defence against cyber threats. Avoid using variations of the same password across multiple accounts—if one gets compromised, all your accounts become vulnerable.


Tips for creating secure passwords:

  • Use a passphrase instead of a single word.

  • Avoid personal details like your name or birthdate.

  • Consider using a password manager such as Bitwarden, Dashlane, or 1Password to store and generate complex passwords securely.

  • Check if your credentials have been compromised by entering your email address at Have I Been Pwned.


Final Thoughts

Taking a few minutes to secure your phone can significantly reduce the risk of data breaches and cyber threats. From keeping your software updated to enabling biometric security and 2FA, these simple steps can go a long way in protecting your personal information. Stay vigilant, update your settings, and enjoy a safer digital experience.
