Multi Device Support

WhatsApp's multi-device architecture allows linked devices to operate independently from the primary phone. WAStack is built on this protocol, meaning your automated sessions remain stable and functional even when the paired phone is offline, out of battery, or disconnected.

The multi-device protocol uses encrypted message syncing across devices. WAStack acts as a linked companion device, receiving messages, sending replies, and maintaining session state independently.

Session stability is enhanced with automatic sync recovery. If a session briefly disconnects, WAStack automatically reconnects and syncs any missed messages. You'll see real-time session health indicators in the dashboard.

This architecture is fundamentally different from older WhatsApp automation tools that required the primary phone to stay online at all times. WAStack's approach is more reliable, more scalable, and aligned with WhatsApp's current platform direction.
