🔐 Step 1: Secure All Your Accounts

Your accounts are the gateway to your digital identity.

✔ Use Strong Passwords

Every account must have a unique, complex password.

Guide:
👉 Strong Passwords

✔ Turn On Multi-Factor Authentication (MFA)

This adds a critical layer of protection.

Guide:
👉 Multi-Factor Authentication

✔ Protect Your Email Above All

Your email can reset the passwords of your other accounts.
Treat it like your digital identity vault.

✔ Update Your Recovery Options

Make sure your:

Backup email
Recovery phone
Security questions

are all secure and up-to-date.

🔒 Step 2: Reduce Your Digital Footprint

✔ Limit Personal Information Online

Avoid posting:

Your full birthday
Phone number
Address
Workplace details
Travel plans
Photos showing sensitive locations

Criminals use this data to impersonate you — see:
👉 Identity Theft Protection

Every platform allows you to control:

Who sees your posts
Who can message you
Tagging permissions
Profile visibility
Location sharing

Guide:
👉 Social Media Scams

If a scammer can use it against you, don’t post it.

🛑 Step 3: Protect Your Devices

Your devices often hold more personal information than your wallet.

✔ Keep Devices Updated

Install updates for:

Operating systems
Apps
Browsers
Security software

✔ Install Trusted Security Software

Anti-malware software helps prevent keyloggers, spyware, and remote access tools.

Guide:
👉 Malware & System Defense

✔ Avoid Jailbreaking or Sideloading Apps

These break core security protections.

✔ Lock Your Devices

Use:

PIN
Password
Biometrics

🌐 Step 4: Protect Your Browsing and Online Activity

✔ Use a Privacy-Focused Browser

Browsers with built-in tracking protection help limit data harvesting.

✔ Enable “Do Not Track”

Not all websites respect it, but it still helps reduce tracking.

✔ Use a VPN on Public Wi-Fi

Public networks expose your browsing and data.
VPNs reduce this risk, especially during travel.

✔ Clear Cookies & Tracking Data Regularly

Tracking cookies slowly build a detailed profile of you.

✔ Use Private or Incognito Mode When Necessary

Useful for sensitive searches but not a full privacy solution.

📱 Step 5: Limit App Tracking & Permissions

Apps often collect:

Contacts
Location
Microphone data
Photos
Browsing history
Device activity

✔ Review App Permissions

Disable unnecessary permissions such as:

Location
Microphone
Camera
Contacts
Bluetooth

✔ Delete Apps You Don’t Use

Each extra app increases privacy exposure.

Logging in with Google/Facebook shares additional data with platforms.

🏦 Step 6: Protect Your Financial Privacy

Your financial data is directly linked to fraud risk.

Scammers exploit messaging platforms heavily.

✔ Monitor Bank & Card Accounts

Look for unusual transactions.

✔ Avoid Public Wi-Fi for Payments

Use mobile data instead.

✔ Use Secure Payment Methods

Avoid sending money to strangers using:

Gift cards
Crypto
Fast payment apps

See:
👉 Payment App Scams

🎭 Step 7: Protect Against AI & Deepfake Risks

Scammers use AI to impersonate you and generate realistic content.

Deepfakes enable:

Fake voice calls
Fake video messages
Fake identity documents
Fake social media profiles

Use secure platforms for document exchange.

🛑 Step 9: What to Do if Your Privacy Is Compromised

Adds strong protection.
