Can WhatsApp Web Work When Your Phone Is Off?

The answer

Yes. Once the device is linked, WhatsApp says linked devices can work without the primary phone being online. The important limit is that linked devices will log out if the primary phone is unused for over 14 days.

Why

The linked-device architecture allows supported devices such as WhatsApp Web to continue operating without a continuous live connection to the phone. The phone is still the primary device for the account, and WhatsApp requires it to be used periodically to keep linked devices connected.

When it is usually OK

• The Web browser or other supported device has already been linked to your WhatsApp account.
• The linked device has its own working internet connection.
• The primary phone has not been unused for more than 14 days.

When you should not

• The browser was never linked to the account.
• The linked device itself has no internet connection.
• The primary phone has been unused long enough for WhatsApp to log out the linked device.

Risks and exceptions

• A shared or unattended browser can remain linked to your WhatsApp account until you log it out or WhatsApp disconnects it.
• Not every WhatsApp feature is supported on linked devices.

Best practice

Use only official WhatsApp Web or supported linked-device apps, review Linked devices from the primary phone, and log out devices you no longer use.

Alternatives

• Use WhatsApp on the primary phone.
• Use the official WhatsApp Desktop app as another supported linked device.
