How to protect your privacy and data?
Is WhatsApp secure?
WhatsApp claims to use end-to-end encryption, meaning only the sender and recipient can access the content of messages. This prevents third parties, including WhatsApp itself, from stealing or tampering with your messages. However, this doesn't mean WhatsApp is entirely secure. In fact, WhatsApp still presents several security threats:
① Account hijacking
If someone gains access to your phone or your verification code, they can log into your WhatsApp account on another device and view/send your messages. This leads to loss of control over your account and information, potentially resulting in scams, ransom, or other forms of attacks.
② Information leakage
Even if your messages are encrypted, if you haven't set a screen lock password or are using unreliable cloud backup services, your messages could still be accessed or copied. For example, if you use Google Drive or iCloud to back up your WhatsApp chats, these backups are no longer protected by end-to-end encryption. This means if someone breaches your cloud storage account or if the service provider faces a hacker attack, your information could be leaked.
③ Privacy infringement
Despite WhatsApp's claim of not collecting or sharing user's personal information, it does share certain metadata with its parent company Facebook, such as phone numbers, device info, location, contact lists, etc. While these metadata may not include message content, they can reveal sensitive information about users' identity, behavior, preferences, etc. Additionally, Facebook might use this information for targeted advertising, data analysis, or other purposes.
How to protect your privacy and data?
Given the security risks associated with WhatsApp, how can you safeguard your privacy and data? Here are some effective methods:
① Enable two-step verification
To prevent unauthorized access to your WhatsApp account, enable the two-step verification feature in settings. This adds an extra layer of security by requiring a six-digit passcode, in addition to the verification code, every time you log in to WhatsApp.
② Use screen lock
Prevent others from accessing or sending messages on your phone when you're away by setting a screen lock password. Additionally, consider using fingerprint or facial recognition for added security.
③ Disable cloud backup
To prevent your information from being stolen by cloud service providers or hackers, disable WhatsApp's cloud backup feature. This ensures your information stays on your phone instead of being uploaded to Google Drive or iCloud. If concerned about data loss, you can use other encrypted backup tools like Signal or Titanium Backup.
④ Adjust privacy settings
To prevent WhatsApp and Facebook from collecting or sharing your personal information, adjust your privacy settings. For instance, you can disable location sharing to prevent WhatsApp from tracking your location. You can also choose not to share your information with Facebook to prevent its utilization. Additionally, you can limit who can see your profile, last seen time, status, etc.
⑤ Use a VPN
To ensure secure online communication, use a Virtual Private Network (VPN) service. VPNs encrypt your internet connection through a secure tunnel, hiding your real IP address and location. This helps evade network monitoring, censorship, and attacks. VPNs also enable access to blocked or restricted websites and services.
