Having to use Google or GitHub to log into Tailscale definitely gave me pause when I was signing up. I actually pumped the brakes for a few months when I first encountered that, but eventually relented and chose GitHub.
I don't particularly _want_ another login, but I also don't cherish the thought of losing access to Service A because of the actions of Service B.
Same here, for something that they pitch as being so self hosted signing up without using your own email was really weird to me. Still haven't signed up....
Yes, that works fine. All non-Workspace services continue to work that way. I discovered it accidentally and I am quite glad that I do not have to migrate many SSO accounts created with Google Apps / G Suite / Workspace over the last decade. The deprecation definitely taught me a lesson in avoiding vendor lockins.
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.
We don't have our own mobile client yet, so right now we rely on the WireGuard app. You configure a gateway, and then generate raw WireGuard configs + QR codes which hook them into the network: https://docs.netmaker.org/external-clients.html
