How is this not scp? (the string `scp` does not exist in the article)
2. tailscale handles key management. this is literally one of its big core competencies btw.
also when did every file copy thing become scp? like if it's not scp why would you expect them to mention it?
No. I'm not even sure why this is a question. The article has instructions on how to use this with macOS, Windows, Linux, iOS, and Android. Both for receiving and sending to each of them. Only two of those OSes are phone OSes.
Same from my iPhone. I can easily send any file to or from any of my devices. It appears in the share menu on my iPhone.
