Tailscale would work as another user said. You could run TOR too. I’ve got a TOR service that I can SSH into for “plan b” if my VPN is down. It doesn’t need port forwarding.

I liked it a lot!

They want your IP or your phone. Use a VPN IP or TOR and they’ll require a phone number. That’s been my experience at least. I don’t trust them.
