Overview
- Scanning a router’s printed Wi‑Fi QR code connects a phone automatically without manual entry.
- On Android, open Settings > Network & Internet > Wi‑Fi > Current network and tap Share to display a QR code for others to scan.
- On iPhone, place another Apple device nearby and approve the on‑screen request to connect without exposing the key in plain text.
- A device already connected to the network can reveal the saved password or generate a shareable QR, depending on the operating system and version.
- Use these options only on private networks, skip third‑party sharing apps, and manage credentials with a password manager and periodic changes.
