As more Nigerians work, bank, and shop online, cybersecurity is more important than ever. Hackers and scammers are getting smarter, but you can stay safe with a few simple habits. Here's how to protect your data, devices, and peace of mind in 2025.
1. Use Strong, Unique Passwords
• Create passwords with a mix of letters, numbers, and symbols.
• Don't reuse passwords across different sites.
• Use a password manager (like LastPass or Bitwarden) to keep track of them.
2. Enable Two-Factor Authentication (2FA)
• Add an extra layer of security to your accounts.
• Use SMS codes, authenticator apps, or biometrics (fingerprint/face ID).
3. Watch Out for Phishing Scams
• Don't click suspicious links in emails, SMS, or WhatsApp.
• Check the sender's address and look for spelling errors.
• When in doubt, contact the company directly.
4. Keep Your Devices Updated
• Regularly update your phone, laptop, and apps to patch security holes.
• Turn on automatic updates where possible.
5. Secure Your Wi-Fi
• Use a strong password for your home Wi-Fi.
• Avoid using public Wi-Fi for sensitive transactions (like banking).
6. Back Up Your Data
• Use cloud storage (Google Drive, Dropbox) or an external hard drive.
• Regular backups protect you from data loss due to theft or malware.
