Setting up Tailscale on iOS

Launch the app and accept the prompts to install a VPN configuration and allow push notifications. (Push notifications serve to alert users that they need to reauthenticate (eg. when keys are about to expire).)
Tap the “Reauthenticate” button to launch the authentication dialog.
Log in using your @gmail.com address.
Congratulations! You’ve added your iPhone to your personal Tailscale network.
