# WhatsApp settings
> The WhatsApp section of the Settings tab is where a project's number is connected and, once connected, where you manage your profile, display name, username, business details, quality rating, and messaging limits.
The **WhatsApp** section of the [Settings tab](/guides/settings-project) is where a project's number is connected and managed.
* **Not connected yet?** You'll confirm you have a Meta Business account and a number that can receive an OTP, then run Meta's embedded signup. The full step-by-step is on [Connect your WhatsApp number](/whatsapp-setup) — this section links you straight into it rather than repeating it.
* **Already connected?** You'll see your profile photo, phone number, display name, and username, along with your quality rating, throughput, and messaging limit — plus a business profile form.
## What you can manage here
* **Profile** — your profile photo and the business profile form: about, description, address, email, and websites.
* **Display name** — the name customers see in their chat list. Changing it is reviewed by Meta before it takes effect.
* **Username** — claim an `@handle` so customers can find you without knowing your number. See [Claim a WhatsApp username](/whatsapp-setup#claim-a-whatsapp-username).
* **Business details** — the industry category sent to Meta, and the rest of your public business information.
* **Quality rating and messaging limits** — Meta's health signals for your number: your current quality rating, your throughput, and how many unique customers you can start conversations with in a rolling 24 hours.
Step-by-step: linking a WhatsApp Business number through Meta embedded signup and setting your display name.
On a phone, Settings sits behind the **☰** menu and each section is its own screen. See [Use Paige on your phone](/guides/mobile-app).
