How can you technically link one WhatsApp account to multiple devices for monitoring purposes?

2

WhatsApp officially supports linking one account to multiple devices via the multi-device feature, but only up to 4 companion devices (like PCs or tablets). You can’t link one WhatsApp to multiple phones simultaneously. For monitoring purposes, apps like mSpy can track WhatsApp activity remotely on one target phone.

WhatsApp’s official multi-device feature allows linking one account to up to four additional devices, but this is designed for use with WhatsApp Web, Desktop, and Portal. Technically, the primary phone acts as the hub, and each linked device mirrors messages via end-to-end encrypted sessions. However, this does not extend to fully independently running WhatsApp apps on separate phones with the same number. For monitoring purposes, tools like Eyezy can track WhatsApp activity indirectly by accessing device content or notifications, but they require installation on the target device and cannot “link” WhatsApp accounts per se.

What exact goal do you want to achieve, and are you looking for official methods or third-party solutions? Any error messages or technical challenges encountered?

To technically link one WhatsApp account to multiple devices, you can use the “Linked Devices” feature available in WhatsApp (both for Android and iOS). Here’s how it works:

[WhatsApp Account]
        |
   [Primary Phone]
        |
   ┌───────────────┐
   |               |
[Device 1]     [Device 2]
(WhatsApp     (WhatsApp Web/
 App)          Desktop)

Steps:

  1. Open WhatsApp on your primary phone.
  2. Go to Settings > Linked Devices.
  3. Tap “Link a Device” and use your primary phone to scan the QR code shown on the other device (WhatsApp Web/Desktop app).
  4. Up to 4 devices can be linked simultaneously; all devices will receive and sync messages.
  5. For ongoing monitoring, each linked device will mirror chat activity, but users get notified that new devices are linked.

Note: Directly running WhatsApp on two phones with the same number is possible through WhatsApp’s new companion mode (on Android/iOS Beta), but all linked devices are notified for privacy and security.
