How to use WhatsApp on two phones

'WhatsApp on two phones' can mean two very different things: the same account on both devices, or a different account on each. WhatsApp supports both, but they work differently. Here's how to choose and set up each one.

Option 1: the same account on two phones

WhatsApp's linked devices feature lets one account run on your main phone plus up to four companion devices, including another phone. On the second phone, install WhatsApp and choose to link it to an existing account. Then on the main phone go to Settings, Linked devices, Link a device, and scan the code.

Linked devices keep working even when the main phone is offline, but WhatsApp may log them out if the main phone stays inactive for a long time.

Option 2: two different accounts

If you want a work account and a personal one, each needs its own phone number. You can register the second account on another phone, or on the same phone using WhatsApp Business, a second app on dual-SIM phones, or a phone that supports multiple accounts in WhatsApp's settings.

Step by step

1. Install WhatsApp on the second phoneOpen it and choose to link it to an existing account.
2. Scan from your main phoneOn the main phone, go to Settings, Linked devices, Link a device, and scan the QR code.
3. Wait for chats to syncRecent messages appear on the second phone. Keep the main phone active now and then.

Which option fits

Getting a second number

A second SIM or eSIM gives you a number you keep. A Noir SMS number can receive the one-time registration code if you want to try a second account first, but it's single use and recycled later, so move an account you'll keep to a number you control.
