So far, the same way it's always worked: you need to BYODomain and sign in with your domain's configured SSO provider. You can't do, say, 3 gmail users.

I’ve always disliked the enforced SSO approach.

However, if you did have 3 Gmail users, it’s possible to share Tailscale access across multiple accounts. So in a small setup you could create an account for each user and then effectively connect their Tailscale networks together (I’m not sure if you can route between Tailscale accounts directly but you can at least share hosts on your account with users on another account, which is how I do it).

I do this with a personal and work account to share some limited access between them.

They also seem to, based on the footnote:

> 4 For historical architectural reasons you cannot currently have more than one user on a “personal” tailnet (such as a gmail.com account). You need either your own domain or a GitHub Organization. Sorry. We will fix this, but not today. Meanwhile, don’t forget that you can use Node Sharing to share devices (including Exit Nodes) across individual tailnets.

Ah so not really all that realistic for personal use with multiple users.
