1) Strong Passwords & Password Manager

Har account par unique, long passphrase use karein. Password manager se sab manage ho jata hai.

Golden rule: Har website/app ke liye alag password rakhein. 12–20 characters ki passphrase best hoti hai—jaise Gulab!Pankha!Neela!2025.

• Dictionary words + numbers + symbols mix karein.
• Passwords ko likhkar ya WhatsApp par share mat karein.
• Password Manager use karein (Bitwarden, 1Password, KeePassXC) — auto-fill, breach alerts & sync.
• Master password ko kabhi share na karein. Recovery codes download karke safe jagah rakhein.

Tip: Quarterly (har 3 mahine) high-risk accounts (email, banking, social) ka password rotate karein.

2) Two-Factor Authentication (2FA) Enable Karein

Authenticator app (TOTP) ya Security key (FIDO2) sabse secure 2FA options.

1. Authenticator App: Google Authenticator / Microsoft Authenticator / Aegis.
2. Security Key: FIDO2/U2F keys (YubiKey, SoloKey) – phishing-resistant.
3. SMS 2FA ko last resort ke roop me use karein (SIM-swap risk).

2FA enable karne ke baad Backup Codes download karke offline save karein (pen drive/printed).

Warning: Same phone par 2FA app + accounts ka single point of failure mat banayein—secondary device ya cloud-encrypted backup rakhein.

3) Phishing se Kaise Bachen?

Unknown links/attachments se bachkar—sender ka domain, grammar aur URL ko hamesha verify karein.

• Hover test: Link par cursor rakhkar asli URL dekhein (mobile par long-press).
• Urgent tone (“abhi verify karein”) ya gift/prize claims → red flag.
• Attachments: .exe, .apk, .scr, .zip ko double-check.
• Bank/UPI ke messages me kabhi OTP/password share na karein.

Spoofed sites se bachne ke liye browser password manager ki saved URLs ka use karein—direct click se fake domain khulne ka chance kam hota hai.

4) Phone & Laptop Hardening (Android/iOS/Windows/macOS)

OS updates, screen lock, disk encryption aur app hygiene—basic par powerful defense.

Essentials

• Auto Updates ON rakhein (OS & apps).
• Lock Screen: PIN/Passcode/Biometric.
• Find My Device enable (remote lock/wipe).
• Encryption enable (FileVault/BitLocker/Android by default).

Extra Safety

• Unknown sources se APK install mat karein.
• Browser extensions ko minimal rakhein.
• Downloads ke liye official stores hi use karein.
• Ad-heavy sites par tracker-blocking browsers (Brave/Firefox) try karein.

5) Backup Strategy: 3-2-1 Rule

3 copies, 2 different media, 1 off-site—ransomware se recovery aasaan.

1. Cloud Backup: Google Drive, iCloud, OneDrive—auto sync ON.
2. Local Backup: External SSD/HDD par weekly backup.
3. Off-site: Ek copy ghar ke bahar/relative ke yahan ya second cloud.

Backups ko time-to-time restore test se verify karein.

6) Public Wi-Fi & VPN Best Practices

Public Wi-Fi par sensitive kaam avoid karein; zaroorat ho to VPN + HTTPS.

• Public Wi-Fi par banking/UPI/login avoid karein.
• VPN use karein (reputed provider), but free VPNs se savdhaan.
• Always check HTTPS (lock icon) before entering credentials.
• Wi-Fi auto-connect OFF; hotspot share karte waqt strong password.

7) App Permissions & Privacy Controls

Location/Contacts/Camera/Mic ko “While using the app” tak limit karein.

Har 2–3 mahine me permissions review karein:

• Location ko precise se approximate par laayen jaha possible ho.
• Background activity/auto-start restrict karein.
• Clipboard, notifications, photo library access ko minimal rakhein.

8) Social Media Safety

Profile ko private, tags/reviews ko approve-first, unknown DMs ko restrict.

Platform	Key Settings	Why
Instagram	Private account, Login alerts, Hidden words filter	Impersonation & scam DMs se bachav
Facebook	2FA, Timeline review, Limit past posts	Old data exposure & profile hijack risk kam
YouTube	Comment moderation, Restricted mode	Spam & harmful links se bachav
X (Twitter)	Password reset protect, DMs allow from followers only	Phishing DMs reduce

9) Parental Controls (Bachchon ke liye)

Screen time limits, content filters, app approvals—family safety ke core tools.

• Android: Family Link, iOS: Screen Time.
• Age-appropriate content filters ON; app installs par approval required.
• Weekly digital safety baatcheet aur cyber-bullying awareness.

10) Quick Security Checklist ✅

Is checklist ko print/save karke monthly review karein.

FAQs

Q. Free antivirus enough hai?

Agar aap safe browsing practices follow karte ho, OS up-to-date hai, aur 2FA enabled hai to basic protection mil jata hai. Business/advanced users ke liye paid suites helpful ho sakte hain.

Q. Data breach me mera email leak ho gaya to?

Immediately password change + 2FA enable. Same password kisi aur site par use kiya ho to waha bhi change karein. Breach monitoring alerts ON rakhein.

Q. Lost phone situation?

“Find My Device” se remote lock/wipe. SIM block ke liye operator ko call. Banking apps ka password/MPIN change.
