Why Do You Need to Open a WhatsApp Account on Two or More Devices?
There are many motivations for operating the same account on multiple phones and devices, including:

- Work continuity: Following important conversations and responding to clients while using a tablet or personal computer without the need for repeated logouts and logins.
- Securing communication: Providing an immediate alternative for conversations in case the primary phone’s battery runs out or is temporarily lost, as the account remains active on the second device.

Conditions for Linking WhatsApp Account on Two Devices

Running WhatsApp on Two Devices with One Number for Android and iPhone
WhatsApp has officially enabled the “Companion Mode,” which is the ideal way to run WhatsApp on two devices with one number for Android and iPhone simultaneously, without the need for the primary phone to stay connected to the internet. To activate this feature, follow the steps below:
1. Install the official WhatsApp application on the second phone (the one to be linked).
2. When you open the app for the first time and reach the phone number entry screen, do not enter your phone number.
3. Tap the three dots icon in the top corner (on Android) or look for available options on the start screen (on iPhone) and choose “Link as Companion Device” to display a QR code on the screen.
4. Go to your primary phone that contains the account and open the WhatsApp application, then follow this path:
– On Android: tap the three dots menu at the top, then choose Linked Devices.
– On iPhone: go directly to the “Settings” menu on the bottom bar, then choose Linked Devices.
5. Click on the “Link Device” option, and scan the QR code shown on the second phone screen using the camera. The conversations will sync immediately and the account will operate on both devices independently.

Open WhatsApp Web Linking with Phone Number (Without Needing QR Code)
If your second device is a computer or laptop, then the Open WhatsApp Web option is the quickest solution for you to communicate while working. The app offers two linking methods:

2. WhatsApp Web Linking with Phone Number
If there is a problem with your primary phone’s camera, you can use the WhatsApp Web linking with phone number by following these steps:
1. Open the WhatsApp Web page in the browser and click on the “Link with Phone Number” option found below the QR code.
2. Enter your phone number linked to the account with your country code, then press “Next” for an 8-digit alphanumeric code to appear.
3. Open the WhatsApp application on your primary phone and go to (Linked Devices -> Link Device).
4. Click on the “Link with Phone Number Instead” option available at the bottom, then enter the 8-digit code shown on the computer screen to complete the linking successfully and securely.

Frequently Asked Questions and Security Facts About Linked Devices
What is the maximum number of devices I can link to my account?
The official multi-device feature allows you to link your main account to up to four additional devices at most (whether other phones via Companion Mode or computers via WhatsApp Web) to all operate simultaneously independently without needing the primary phone to be connected to the internet.
Can I open a WhatsApp account for someone else without their knowledge?
From a technical and security standpoint, the WhatsApp application enforces a strict encryption system that completely prevents access to any other party’s conversations without their knowledge or consent. The only official way to link the account to a second device requires direct and physical access to the primary phone to perform the QR code scanning or receive the confirmation code, making it impossible to activate the account remotely without the owner’s direct permission.
How can I ensure the protection of my privacy and my account from spying?
To protect the security of your data and personal conversations, it is advised to follow these precautionary measures:
- Make sure to enable the “Automatic Backup” feature for your conversations in the cloud via Google Drive or iCloud regularly to avoid data loss when switching between devices.
- Visit the Linked Devices list in your application periodically; if you notice any active device or browser you do not recognize, press it and select “Log Out” immediately to cut the connection and unlink it.
- Enable app lock using fingerprint or face recognition to prevent anyone from tampering with your account settings or scanning the linking code in your absence.
