Multi-device WhatsApp Business in 2026 comes in two versions: the app allows you to link up to four secondary devices to the main phone (five accesses in total, without roles or metrics), or the WhatsApp Business API with a platform like Aurora Inbox, which supports unlimited agents with roles, automatic routing, and individual reports. For sales teams of one to four people, the app works; for teams of more than five, it falls short, and a migration is necessary.
What is WhatsApp Business multi-device?
This feature allows multiple people to use the same WhatsApp Business number simultaneously from different devices. The primary phone (where the number is registered) plus up to four secondary devices—a total of five accesses.
Configure multi-device support in the WhatsApp Business app
Step 1: Make sure the app is up to date
Minimum version: WhatsApp Business 2.24.x for Android, 24.x for iOS. Update from the Play Store or App Store.
Step 2: Link secondary devices
- On the main phone: Settings → Linked devices → Link a device.
- On the secondary device (computer, tablet, or additional phone), open web.whatsapp.com.
- Scan the QR code with your main phone.
- The secondary device remains linked and can read/respond to the same chats.
Repeat up to 4 times to reach the limit of 5 accesses.
Step 3: Configure basic permissions
The app doesn't allow roles, but you can:
- See which devices are linked from the main phone.
- Log out remotely on any device.
- Receive notifications of suspicious activity.
Limitations of multi-device support in the app
Five critical limitations when scaling:
- Hard stop with 5 access points. If your team grows to 6 people, someone will be left out.
- Without roles or permissions. Everyone sees everything, anyone can reply to any chat.
- Without automatic routing. The customer goes to whoever arrives first.
- No reports per agent. You don't know who answered whom, or how long it took.
- Without an AI agent. The app does not support AI with RAG or tools (scheduling, catalog).
For serious sales teams, these limitations are operationally fatal.
Professional multi-device: API + Aurora Inbox
As the team grows, the WhatsApp Business API with a platform like Aurora Inbox provides:
- Unlimited agents (limited only by your plan).
- Roles and permissions (admin, supervisor, agent, reader).
- Automatic routing by department, language, time of day, or round-robin.
- Attribution and reassignment manual or automatic chats.
- Individual metrics — response time, conversions, agent satisfaction.
- AI Agent which filters before passing to humans.
- Multichannel (WhatsApp, Messenger, Instagram, TikTok all from the same inbox).

How to set up Aurora Inbox for a sales team
Step 1: Create an account and connect your number
Start your free trial and connect your WhatsApp Business number via OAuth. 10 minutes.
Step 2: Create users for each agent
In Aurora Inbox, Users → InviteEach user receives an email to activate their account. Assign role:
- Admin — total control, user management and configuration.
- Supervisor — View all conversations, full reports, do not edit global settings.
- Agent — only view assigned conversations, reply, and add notes.
- Reader — read-only, useful for managers.
Step 3: Define routing rules
In Settings → RoutingConfigure:
- By department. Messages that mention "invoice" → accounts team; "demo" → sales team.
- By language. Messages in English → international team.
- By schedule. After 6:00 PM → AI + human on duty.
- Round-robin. Equitable distribution among active agents.
Step 4: Configure the AI agent as the initial filter
Any incoming conversation first passes through the AI agent, which:
- Say hello and understand the reason.
- It answers frequently asked questions based on RAG.
- Qualify leads (budget + timing + need).
- Scale to the right human when needed.
Step 5: Activate individual metrics
Aurora Inbox tracks by agent:
- Average first response time.
- Average resolution time.
- Conversion rate.
- CSAT at closing time.
- Volume of chats handled.
Available in 7 dashboards for managers.
Step 6: Configure scaling and reassignment
Typical rules:
- If an agent does not respond within 5 minutes, reassign.
- If the client asks for a "supervisor", escalate to the Supervisor role.
- If the AI detects a serious complaint, escalate it to a specialist.
Costs: app vs Aurora Inbox
| Concept | Multi-device app | Aurora Inbox |
|---|---|---|
| Subscription | $0 | $99 USD/month (3 users) |
| Additional users | N/A (maximum 5) | $13 USD/user/month |
| AI with RAG | No | Included in AI plans |
| Meta Conversations | $0 (no API) | Variable by country |
For 10 agents in Aurora Inbox: $99 + 7 × $13 = $190 USD/month.
Common mistakes
- Force the app beyond 5 accesses. You look for options like sharing accounts, which ends up getting you banned.
- No routing rules. Everything falls into the same category and response time collapses.
- No metrics per agent. Without data, there is no management.
- Do not use an AI agent as a filter. Your team is burning out handling queries that AI could solve.
- Permits that are too open. Everyone as "admin" is risk and chaos.
