Tailscale n00b questions - Reddthat

Playing around with a new self-host NAS OS, finally thought about Tailscale. But, I see it wants a login to an account. Checking online, seems I have to use Google, Apple, MS, Github or OIDC (which iassume costs money based on the site). So how tf y’all setting to your tail scale stuff? I’m not using a big brother us tech account for auth on this thing. Think I’d rather go back to regular wireguard if that’s the case.
