Problem

WhatsApp accounts can be vulnerable to unauthorized access if someone gains your SIM card or verification code. Without extra security, hackers could take over your account.

Solution

Enable two-step verification in WhatsApp to add a PIN and optional recovery email. This ensures that even if someone has your SIM card, they can’t activate WhatsApp without your PIN.

Best Practices / Tips

• Always add a recovery email when enabling two-step verification.
• If you forget your PIN and didn’t set a recovery email, you’ll have to wait 7 days to reset.
• Be cautious of phishing attempts — WhatsApp will never ask for your PIN or SMS code by message or call.
• Combine two-step verification with strong device security (screen lock, biometrics).
