WhatsApp PIN codes to prevent unwanted messages from coming to your usernames

Scams and spam are becoming more common on WhatsApp. For example, some people are receiving fake messages from alleged contacts like Rosa Caro Serrano or are tricked into trying to steal their accounts using a six-digit code. To address these issues, Meta, the company behind WhatsApp, is constantly working to improve the security of the app. Meta recently announced a new feature: WhatsApp will soon be able to automatically block messages from unknown contacts.

How to Strengthen WhatsApp Security: What's Coming and How to Stay Safe

One of the most exciting upcoming features is the introduction of usernames. This will allow users to create unique usernames, similar to those on Telegram or Signal. With usernames, people can communicate with each other without sharing phone numbers.

While usernames help protect privacy by keeping phone numbers private, they also have a potential downside. If someone’s username is easy to guess, they may receive messages from strangers. This happens a lot on platforms like Telegram, where users often receive messages from unknown people. Telegram solves this problem by allowing users to automatically archive messages from strangers to reduce spam.

To address this issue on WhatsApp, Meta is testing a new feature that involves a PIN system. According to WABetaInfo, this feature is currently in WhatsApp for Android beta version 2.24. 18.2, but it is not live yet. The idea is that users will be required to set a PIN code. When someone tries to send a message on behalf of a user, they will be required to enter this PIN code if they have not interacted with the user before. This adds an extra layer of security by ensuring that only those who know the PIN code can send messages on behalf of that user.

This PIN system is optional, meaning users can choose whether or not to use it. It only applies to messages sent on behalf of a username, so messages sent directly to a phone number will continue as usual.

It’s important to remember that usernames aren’t officially available on WhatsApp yet. Users will need to wait for Meta to fully implement the feature. In the meantime, being vigilant and careful about sharing personal information is essential to protect yourself from scams and spam.

As a result, WhatsApp is taking significant steps to improve security and privacy. The introduction of usernames and the PIN system are designed to protect users from spam and scams. As Meta continues to improve these features, users can expect a more secure and private messaging experience.

Tips to Improve WhatsApp Security and Privacy

1. Use Strong and Unique PIN Codes:

   • When the PIN feature is available, create a strong, unique PIN. Avoid using easily guessed numbers or codes that overlap with other security codes, such as those used to unlock your phone or access financial accounts.

2. Enable Two-Step Verification:

   • To add an extra layer of security, enable WhatsApp's two-step verification. This feature requires you to enter a PIN when registering your phone number with WhatsApp and provides additional protection against unauthorized access.

3. Pay attention to your username:

   • While usernames can increase privacy, they should still be chosen carefully. Avoid using usernames that are easily identifiable or associated with your personal information. A unique and less obvious username helps reduce the risk of unwanted contact.

4. Share Your PIN Wisely:

   • Only share your PIN with people you trust. Avoid sharing it in public forums or with people you don't know well. This will help prevent unauthorized users from accessing your account.

5. Monitor and Manage Privacy Settings:

   • Regularly review and update your privacy settings in WhatsApp. You can control who can see your profile picture, status updates, and last seen information. Adjust these settings to limit visibility to only people you trust.

6. Beware of Unwanted Messages:

   • Be careful if you receive messages from unknown people. Avoid clicking on suspicious links or sharing personal information. Report and block people who appear suspicious or send unwanted messages.

7. Update WhatsApp Regularly:

   • Keep your WhatsApp app updated to benefit from the latest security patches and feature improvements. Meta frequently releases updates that improve security and fix vulnerabilities.

8. Use Strong Device Security:

   • Make sure your smartphone is protected with a strong password, PIN, or biometric authentication (like fingerprint or facial recognition). This adds an extra layer of security to your WhatsApp account and other personal data.

9. Beware of Phishing Attempts:

   • Be wary of phishing attempts that may try to reveal your verification codes or other sensitive information. WhatsApp will never ask for your verification code via email or text message.

10. Educate Yourself About New Features:

    • Stay informed about new features and updates in WhatsApp. Understanding how new features, like usernames and PINs, work will help you use them effectively and increase your security.

11. Manage Active Sessions:

    • Regularly check and manage active sessions on WhatsApp Web and desktop apps. Log out of any sessions you don't recognize or no longer use to prevent unauthorized access.

12. Backup Your Data Safely:

    • Backup your WhatsApp chats and media regularly, but make sure the backup is encrypted and stored securely. This will help protect your data in case of device loss or other issues.

By following these tips, WhatsApp users can better protect their accounts and personal information from potential threats and privacy breaches.
