Tailscale (any platform)

Reach home devices from anywhere. Uses the same tutu.casa account (passkey) as everything else — no separate password.

1. Install the Tailscale app (App Store / Play Store / tailscale.com/download).
2. Before signing in, set a custom login server:
   • iPhone/iPad: in the app, tap the account/login menu → Use a custom coordination server and enter https://sc.tutu.casa.
   • Android: open the app menu (⋮) → Use an alternate server → https://sc.tutu.casa.
   • Windows/Mac/Linux: tailscale login --login-server https://sc.tutu.casa
3. Sign in — the browser opens the familiar tutu.casa passkey login.
4. Done. Home addresses (192.168.1.x, 192.168.100.x) and names like ha.tutu.casa work while the VPN is on.

Optional: enable the exit node ("tutu router") to route ALL your traffic through home. Note IPv6 through the exit node is currently unreliable (ISP issue) — leave exit node off if a site misbehaves.
