1. Set Strong Passwords and Enable Screen Lock
One of the most basic yet overlooked steps in mobile security is setting strong screen locks:
- Use alphanumeric passwords or pattern locks instead of simple 4-digit PINs.
- Enable biometric security: fingerprint or facial recognition, depending on your device.
- Change passwords regularly and avoid using personal information like birthdays.

TJ News Nigeria gathered that many hacking cases in Nigeria started with stolen or lost phones lacking screen protection.
2. Activate Two-Factor Authentication (2FA)
Two-Factor Authentication (2FA) adds an extra layer of security to your online accounts:

- Enable 2FA for all important apps, especially for:
- Banking apps (Opay, PalmPay, Kuda, etc.)
- Email accounts (Gmail, Yahoo Mail)
- Social media (Facebook, Instagram, WhatsApp)
Use authentication apps like Google Authenticator or Authy instead of SMS codes alone for added safety.
3. Beware of SIM Swap Fraud
SIM swap scams are on the rise in Nigeria. Hackers trick telecom operators into transferring your phone number to another SIM, gaining access to your calls, texts, and OTPs.
How to Protect Against SIM Swap:

- Activate SIM lock PIN: Dial *746# on MTN, Airtel, Glo, or 9mobile.
- Link your SIM to your NIN properly at authorized telecom centers.
- Immediately contact your network provider if your phone suddenly loses service.
4. Download Apps Only from Trusted Sources
Avoid downloading applications from random websites or third-party app stores. Stick to:
- Google Play Store for Android
- Apple App Store for iPhones
- Check app reviews and developer credibility before installation.
Warning signs of fake apps:
- Too many permissions requests (e.g., access to contacts, messages, or microphone unnecessarily)
- Numerous spelling errors or poor-quality app logos
5. Avoid Public Wi-Fi for Sensitive Transactions
Public Wi-Fi in cafes, airports, or parks is often unsecured, making it easy for hackers to intercept data.
Protect yourself by:
- Using VPN services (Virtual Private Network) when accessing public Wi-Fi
- Avoiding banking or financial transactions over unsecured networks
6. Update Your Phone Software Regularly
Software updates often contain patches for security vulnerabilities:
- Enable automatic updates for your phone’s operating system (Android/iOS).
- Regularly update apps, especially banking and social media apps.
- Outdated phones (Android 8 or lower) should be upgraded or replaced for better security.
7. Be Careful With Links in SMS, WhatsApp, or Emails
Phishing scams are widespread in Nigeria. Hackers send fake messages posing as:
- Banks
- Delivery companies
- Social media platforms
- Government agencies (e.g., NIN updates)
How to stay safe:
- Don’t click on links from unknown senders.
- Verify any requests by calling official customer care lines.
- Use browsers that warn against malicious sites (e.g., Google Chrome, Brave).
8. Enable Remote Tracking and Wipe Features
In case of theft or loss:
- Android: Activate Find My Device (via Google settings)
- iPhone: Use Find My iPhone from your iCloud account
- These features can help you locate, lock, or erase your data remotely.
9. Use Antivirus and Anti-Malware Apps
Reliable antivirus software helps detect malicious apps or activities:
- Recommended antivirus apps: Avast Mobile Security, Kaspersky Mobile, Norton
- Avoid using cracked or free versions from untrusted sources.
10. Regularly Back Up Your Data
Use Google Drive, iCloud, or external storage devices to regularly back up:
- Contacts
- Photos
- Important documents
If your phone is compromised or lost, your essential data remains safe.
