Phone sign-up → profile → linked devices → 2FA → Google Drive or iCloud backup.

Register and verify your phone
Open WhatsApp, accept terms, pick your country, and enter your phone number. Confirm the SMS code (voice call is available on some networks). Set a display name. One number maps to one account; desktop cannot create a brand-new account without the phone first.

Link devices
On phone: Settings → Linked devices → Link a device, then scan the QR at web.whatsapp.com or in WhatsApp Desktop. Review linked sessions and log out anything unfamiliar. The phone remains the primary device.

Enable two-step verification
Settings → Account → Two-step verification → Enable. Choose a 6-digit PIN, add a hint, and bind a recovery email. New installs on your number need SMS plus PIN if SIM swapping is a risk. Store the PIN safely — recovery options are limited by design. See faq.whatsapp.com.

Back up to Google Drive or iCloud
Settings → Chats → Chat backup. Android: pick a Google account, schedule backups, optionally include videos, tap Back up. iPhone: turn on iCloud backup (uses Apple ID storage). Before replacing a phone, back up on Wi‑Fi and sign in with the same number on the new device to restore.
Backups matter
Without backup, chat history may not return after a reinstall or lost phone.
Linked desktop
Desktop/Web mirrors the phone — not a separate login forever.
PIN vs SMS
SMS proves SIM access; the PIN is an extra lock on re-registration.
| Capability | Mobile | Linked / Desktop |
|---|---|---|
| New account (phone) | Yes | Phone required first |
| Messaging | Yes | Yes (needs phone online) |
| Chat backup | Google / iCloud | Set on phone |
| Two-step PIN | Yes | Applies on new login |
What this has to do with a browser canvas
WhatsApp handles messaging. If you only need a live flow sketch with teammates, try the rtcroom home page for a no-install, no-signup board — see create and join a space or the Telegram setup guide.
Still wondering?
Can I skip backup?
You can chat daily, but history may be gone after a device change. Turn on automatic backup in Chat backup.
Changing phone numbers?
Use Settings → Account → Change number and verify both old and new SIMs. Back up first.
Forgot the PIN?
Recovery email can reset it; otherwise you rely on your hint. WhatsApp will not bypass PIN checks.
