I'd like to offer Netmaker as an alternative. Caveat, I'm one of the creators so grain of salt, etc. It's completely self-hosted, so none of your traffic will go through our servers. You can also use basic auth by default (though there is also OAuth). Finally, as a bonus, it's much faster because you can use kernel WireGuard. I won't claim it's as user-friendly as Tailscale (yet). It definitely requires more technical knowledge to set up, especially considering it's not a SaaS. But if you're willing to get through the initial setup (Day 0 / Day 1), you should be golden.
