Setting up Tailscale on iOS
Tailscale can run on iOS 12.0 or higher. It supports both iPhone and iPad.
Download Tailscale from the App Store.
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, and log in using your SSO provider.
Check out Next Steps for steps on verifying that even a single endpoint is working. With multiple endpoints, simple pings are a good way to start.
Congratulations! You’ve added your iPhone (or iPad) to your Tailscale network.
