In 2026, cyberattacks are more sophisticated than ever. Yet the vast majority exploit simple flaws that anyone can fix. Here are the 10 practices that really make a difference.

1. Use a unique password for each account

Reusing the same password is the first mistake to avoid. If one site is compromised, all your other accounts are too. Use a password manager like Bitwarden (free) or 1Password.

2. Enable two-factor authentication (2FA)

2FA adds an essential layer of protection. Even if your password is stolen, an attacker won't be able to access your account without the second factor. Prefer an authentication app (Authy, Google Authenticator) over SMS.

💡 Priority: First enable 2FA on your most important accounts: email, banking, social media.

3. Update your software systematically

Most cyberattacks exploit known vulnerabilities for which patches already exist. Enable automatic updates on your operating system, browser and apps.

4. Be wary of unsolicited emails and messages

Phishing remains the #1 attack vector. Before clicking a link or downloading an attachment, check the sender's address and hover over links to see their real destination.

5. Use a VPN on public Wi-Fi networks

Public Wi-Fi networks (hotels, cafes, airports) are easy targets for hackers. A VPN encrypts your connection and protects your data in transit.

6. Back up your data regularly

The 3-2-1 rule: 3 copies of your data, on 2 different media, with 1 offsite (cloud). In case of ransomware or failure, you'll be able to restore everything.

⚠️ Warning: A backup on the same device or network as ransomware can also be encrypted. Keep at least one disconnected copy.

7. Check your app permissions

Many apps request excessive access (camera, microphone, contacts, location). Regularly review permissions in your phone settings and revoke what's unnecessary.

8. Use a secure browser with good extensions

Brave or Firefox with uBlock Origin automatically block the vast majority of malicious ads and trackers.

9. Protect your email account first

Your email is the key to all your other accounts (password reset). A compromised email potentially means all your accounts compromised. Secure it with a strong password and 2FA.

10. Educate yourself and those around you

Cybersecurity is everyone's business. Share these best practices with your family and colleagues. The majority of security incidents involve human error.

Summary

  • Unique password per account + password manager
  • 2FA enabled on all important accounts
  • Automatic updates enabled
  • Regular backups (3-2-1 rule)
  • Constant vigilance against suspicious emails and messages
