How to find out if someone else is checking my WhatsApp by phone number - in detail?

To determine if someone else is accessing your WhatsApp account using your phone number, you need to be vigilant and look for specific signs. Here are the detailed steps and indicators that can help you identify unauthorized access:

1. Two-Factor Authentication (2FA): Ensure that 2FA is enabled on your WhatsApp account. This adds an extra layer of security, as any attempt to log in from a new device will require a unique code sent to your registered number or email. If you receive such a code unexpectedly, it might indicate someone trying to access your account.
2. Login Notifications: WhatsApp provides notifications for each login on a new device. Check the app's settings to ensure these notifications are enabled. Any unexpected notification about a new login can alert you to potential unauthorized access.

3. Unusual Activity: Keep an eye out for any unusual activity on your account. This could include:

   • Messages or calls made from your account that you did not initiate.
   • Changes in your profile picture, status, or other settings without your knowledge.
   • New contacts added to your list that you do not recognize.
   • Unusual data usage, especially if your device is not actively being used.
4. Device Management: Regularly check the list of devices connected to your WhatsApp account. You can find this under "Linked Devices" in the app's settings. If you see any unfamiliar devices listed, it indicates someone else might be using your account.
5. Security Code: WhatsApp uses a security code for device verification. This code is unique to each device and changes if the number is used on a new device. If you notice that the security code has changed unexpectedly or receive notifications about code changes, it could signal unauthorized access.
6. Check Login History: WhatsApp allows you to view your login history, which includes information about devices where your account was recently used. This feature can help you identify any unrecognized devices or logins.
7. Account Settings: Regularly review your account settings for any changes that you did not make. This includes checking the "Two-step verification" and "Linked Devices" sections to ensure no unwanted modifications have been made.
8. Use WhatsApp Web/Desktop Responsibly: If you use WhatsApp Web or Desktop, be cautious about where you log in. Avoid using public or shared computers, as this can increase the risk of unauthorized access.

By staying attentive to these signs and taking proactive measures to secure your account, you can effectively monitor for and respond to any attempts by others to check your WhatsApp by phone number.
