Cloud storage is convenient.
But without proper security, it’s like leaving your house door unlocked — with all your valuables inside.
Here’s how to protect your files in the cloud properly.
✅ 1. Always use strong, unique passwords
-
Never reuse old passwords from other sites
-
At least 12+ characters, mixed types (letters, numbers, symbols)
-
Use a password manager to store them safely
✅ First defense is your login itself.
✅ 2. Enable Two-Factor Authentication (2FA)
-
Google Drive → Use Google Authenticator or phone prompt
-
Dropbox → Enable Authenticator app-based 2FA
-
OneDrive → Add a second verification step via Microsoft Authenticator
Even if your password leaks, 2FA protects your account.
✅ 3. Audit third-party app access
Over time, many apps (like scanners, note tools, etc.) request cloud access.
-
Review connected apps → Remove ones you don’t recognize
-
Limit permissions (view-only vs edit rights) where possible
✅ Old, forgotten apps are a common entry point for breaches.
✅ 4. Encrypt sensitive files before uploading
-
Use VeraCrypt to create encrypted containers
-
Or zip files with AES-256 encryption (7-Zip supports this)
Even if your cloud account is hacked, encrypted files stay safe.
✅ 5. Monitor login activity
-
Google Drive → Check “Recent Security Activity”
-
Dropbox → Security → Devices + Sessions
-
OneDrive → View Account Sign-ins
✅ Look for strange IP addresses, devices, or login times.
Key points to remember
-
Strong passwords + 2FA = must-have basics
-
Audit and remove unnecessary app permissions
-
Encrypt sensitive files before upload
-
Watch your login history regularly
-
Cloud is safe — only if you manage it smartly
