How to find out which device was used to log into WhatsApp on my phone - in detail?

To determine which device was used to log into your WhatsApp account on your phone, follow these detailed steps:

1. Check the Login History:

   • Open the WhatsApp application on your phone.
   • Navigate to the settings by tapping on the three dots (⋮) in the upper right corner and selecting "Settings."
   • Go to "Account" and then tap on "Security."
   • Here, you will find an option labeled "Devices with recent activity." This section lists all devices that have recently accessed your WhatsApp account. Each device will be displayed with a timestamp indicating when it was last used.

2. Review Device Information:

   • Tap on any of the listed devices to get more information about it, including the device type (Android or iPhone), operating system version, and the last login time.
   • This information can help you identify if an unknown device has accessed your account. If you find a device that you do not recognize, WhatsApp provides an option to log out from that specific device.

3. Log Out from Unrecognized Devices:

   • To enhance security and prevent unauthorized access, tap on the three dots (⋮) next to any unfamiliar device listed under "Devices with recent activity."
   • Select "Log Out" to immediately terminate that session. This will require the user of that device to scan a QR code again to regain access to your account.

4. Enable Two-Step Verification:

   • For added security, enable two-step verification within WhatsApp settings. Go to "Account" > "Two-step verification," and follow the prompts to set it up. This feature requires a six-digit PIN when registering your phone number with WhatsApp.

5. Check for Suspicious Activity:

   • Pay attention to any suspicious messages or notifications that might indicate unauthorized access. If you receive a message stating that your phone number has been registered on another device, take immediate action by logging out from all devices and enabling two-step verification.

By following these steps, you can effectively monitor and manage which devices have access to your WhatsApp account, ensuring the security and privacy of your communications.
