Whether you’re using an Android or iPhone, these tips will help you stay one step ahead of cyber threats.


1. Use a Strong Screen Lock

The first line of defense for your smartphone is a strong screen lock. Avoid simple patterns or PINs and opt for more secure methods.


Options:

  • Fingerprint Scanner: Fast and secure.
  • Facial Recognition: Convenient and advanced.
  • Complex PIN/Password: At least 6 digits with a mix of numbers and letters.


How to Set It Up:

  • On iPhone: Go to Settings > Face ID & Passcode or Touch ID & Passcode.
  • On Android: Go to Settings > Security > Screen Lock.


2. Enable Encryption

Encryption ensures that your data is unreadable to anyone without the correct credentials.


How to Enable It:

  • On iPhone: Encryption is automatically enabled when you set a passcode.

Public Wi-Fi networks are often unsecured, making them a hotspot for hackers.


What to Do Instead:

Use your mobile data or a VPN (Virtual Private Network) to encrypt your connection.


5. Use a VPN

A VPN encrypts your internet traffic, making it difficult for hackers to intercept your data.


Recommended VPNs:

  • ExpressVPN
  • NordVPN
  • Surfshark


6. Enable Two-Factor Authentication (2FA)

2FA adds an extra layer of security by requiring a second form of verification.


How to Enable It:

  • For Google accounts: Go to myaccount.google.com > Security > 2-Step Verification.
  • For Apple ID: Go to Settings > [Your Name] > Password & Security > Two-Factor Authentication.


7. Download Apps Only from Official Stores

Third-party app stores can host malicious apps. Stick to Google Play Store and Apple App Store.


How to Check App Permissions:

Before downloading, review the permissions the app requests.

This feature helps you locate your phone if it’s lost or stolen.


How to Enable It:

9. Be Cautious with Links and Attachments

Phishing attacks often use malicious links or attachments to steal your data.


What to Do:

  • Avoid clicking on links in unsolicited emails or messages.
  • Verify the sender’s identity before opening attachments.


10. Regularly Back Up Your Data

Backups ensure that you don’t lose your data if your phone is compromised.


How to Back Up:

  • On iPhone: Use iCloud or iTunes.
  • On Android: Use Google Drive or a third-party app.


11. Disable Bluetooth When Not in Use

Leaving Bluetooth on can make your phone vulnerable to attacks.

Antivirus apps can detect and remove malware.


Recommended Apps:

Encrypted messaging apps protect your conversations from prying eyes.
