Are you using some Apple or MS author account?
Google and Github SSO were the only options when I originally setup tailscale. There are a few more options now including what looks like every self-hosted OIDC provider I’ve ever heard of, and a few I hadn’t.
How did you config tail scale though?
There are a couple options depending on how you are using it. Most of the time I just use the tailscale command to configure each node.
Most systems were just sudo tailscale up --ssh to get it up and running, although I have one system setup as a subnet router to give me outside-the-house access to systems that I can’t put tailscale on. That was a little more involved but it was still pretty straightforward and well documented. Their documentation is actually very well written and is worth the read.




I don’t know of any sftp programs specifically, but any file sync program should work.
It would be massive overkill for this one task, but I personally use my Nextcloud server to move files on and off my iPhone to my services as needed. I have the Jellyfin media directory, Calibre upload, and Paperless upload directories mounted in Nextcloud as external directories (as SFTP mounts, I think) and then access them from my phone from the Nextcloud app.
