• See the full SMTP headers of an email, specially useful when you are trying to track down which email alias spam was addressed to.
  • Use an external UVC camera instead of the built-in one. I don’t trust the Mac Zoom app with its horrendous security record and the iOS sandbox is much more secure, but I’d also like to use my Sony RX1RII camera with an Elgato Camlink 4K for its superior image quality. Yes, I know using the web-based Zoom client is much more secure for you (because it is also sandboxes, in this case by the browser), but it also lacks end-to-end encryption.
  • SSH using ed25519-sk keys backed by a U2F hardware key like a Yubikey or trusting SSH certificates (yes, I know Termius supports it but subscription software is never acceptable).
