How to find out if someone else is reading my WhatsApp on another device - in detail?

To determine if someone else is reading your WhatsApp messages on another device, you need to be vigilant and look for several key indicators. Here are detailed steps to help you identify unauthorized access:

1. Check for Unusual Activity: Monitor your account for any unusual activity that could indicate someone else is using it. This includes:

   • Messages being read or delivered when you're not active on the app.
   • Changes in your last seen status that don’t correspond to your usage.
   • Unexplained changes in your profile picture, status, or about section.

2. Verify Device List: WhatsApp allows users to see all devices linked to their account. Here's how you can do it:

   • Open WhatsApp and go to Settings.
   • Select Linked Devices. This option will show a list of all devices where your WhatsApp is active. If you find an unknown device, it’s a clear sign that someone else has access to your account.

3. Review Active Sessions: Similar to checking linked devices, reviewing active sessions can help identify unauthorized access:

   • Go to Settings in WhatsApp.
   • Navigate to Linked Devices and look for any active sessions on devices you don’t recognize.

4. Enable Two-Step Verification: This feature adds an extra layer of security to your account. If someone tries to log in from a new device, they will need the verification code sent to your phone:

   • Go to Settings in WhatsApp.
   • Select Account and then Two-step Verification.
   • Follow the prompts to set it up.
5. Monitor Message Timestamps: Pay attention to the timestamps on your messages. If you see that a message has been read or delivered at a time when you weren’t using WhatsApp, this could indicate unauthorized access.
6. Check for Unusual Logins: WhatsApp will sometimes notify you of new logins from unknown devices. These notifications can be crucial in detecting someone else reading your messages.

7. Use Security Codes: If you’re concerned about unauthorized access, consider using security codes to log into your account on a new device:

   • When setting up WhatsApp on a new phone, you'll be prompted to enter a code sent to your primary phone number. This ensures that only you can access your account from new devices.
8. Regularly Review Linked Devices: Make it a habit to periodically review the list of linked devices and active sessions in WhatsApp. This proactive approach can help you quickly identify and address any suspicious activity.

By following these steps, you can effectively monitor your WhatsApp account for signs of unauthorized access and take appropriate action to secure your communications.
