1. How to Use Two-Factor Authentication Everywhere

  • Enable two-factor authentication (2FA) on every account that offers it, including email, social media, cloud storage, and banking.
  • Choose an authenticator app (e.g., Google Authenticator, Microsoft Authenticator, Authy) instead of SMS for stronger security.
  • On each site or app, visit “Security settings” and follow prompts for 2FA setup—scan the QR code with your authenticator app.
  • Save backup codes offline in a safe place in case you lose access to your device.
  • Avoid using email or SMS for 2FA on critical accounts whenever possible.

  • Use in-built tools: Microsoft Family Safety (Windows), Apple Screen Time (iOS/Mac), Google Family Link (Android/Chromebook).
  • Set app, web, and game time limits, block explicit content, and monitor app downloads.

3. How to Choose the Right Laptop for Work, Study, or Gaming

  • Define your main use-case: work (office apps, video calls), study (portability, battery), or gaming (graphics, RAM).
  • Look for at least 8GB RAM for everyday use, 16GB+ for gaming or heavy multitasking.
  • Choose SSD storage over HDD for speed. Prefer 512GB SSD or higher for gaming and creative work.
  • For gaming, ensure a dedicated GPU (NVIDIA/AMD). For work or study, integrated graphics suffice.
  • Check battery life, build quality, keyboard/trackpad comfort, after-sales service, and upgradability.

4. How to Troubleshoot Common Tech Issues Like a Pro

  • Restart the device—solves most “stuck” problems instantly.

5. How to Create Strong Passwords and Manage Them Securely

  • Use long, random passwords with a mix of letters, numbers, and special characters; avoid common words or patterns.
  • Do not reuse passwords across multiple sites—unique for every account.
  • Adopt a reputable password manager (like Bitwarden, Dashlane, 1Password) to store and autofill credentials securely.
  • Enable biometric login or a master password with 2FA to protect your password manager.
  • Change passwords immediately if you suspect an account has been compromised.
