How to make only contacts able to write in WhatsApp - in detail?

To ensure that only your contacts can message you on WhatsApp, follow these detailed steps:

1. Update WhatsApp: Make sure your WhatsApp application is up-to-date. An outdated version may not have the latest privacy features.
2. Access Privacy Settings: Open WhatsApp and navigate to "Settings." This can typically be found in the lower right corner of the screen (on Android) or by tapping on the profile picture in the top left corner (on iOS).
3. Account Privacy: Within the settings menu, select "Account" followed by "Privacy." Here you will find various options to control who can see your personal information and message you.
4. Last Seen & Read Receipts: While these options do not directly prevent non-contacts from messaging you, they do affect the visibility of your activity status. You can choose "Nobody," "My Contacts," or "Everyone" based on your preference.
5. Profile Photo: Similar to the above, you can control who sees your profile picture by selecting either "Nobody," "My Contacts," or "Everyone."
6. Status Privacy: WhatsApp allows you to set privacy for your status updates. Choose "My Contacts" so only those in your contact list can view your status.
7. Block Non-Contacts Manually: If a non-contact tries to message you, you have the option to block them directly from the chat screen. Blocking prevents the user from sending further messages and calling you.
8. Two-Step Verification: Enable two-step verification for an added layer of security. This feature ensures that even if someone tries to register your number on WhatsApp, they will need a PIN code that only you know.
9. Privacy Settings for Groups: To prevent strangers from adding you to groups, go to "Settings," then "Account" > "Privacy" > "Groups." Choose the option "Nobody" or "My Contacts" depending on your preference.

By following these steps, you can significantly enhance your privacy on WhatsApp, ensuring that only your contacts are able to message you directly.
