Awesome, I would also add a link to it in the authentication.md page. Perhaps add a section for "Instance authentication", that talks links to the OIDC page?

@josevalim Done.

I did it very simply because we may need to improve how we organize auth pages inside our docs. For example, there's also the "use Teams account" feature that we'll already have, and the "email domain" one we're working on.

I thought about reorganizing the whole auth docs structure now, but I believe it's better to ship this PR and address the organization in a future PR.

What do you think?

I pushed some docs, cause I wanted to rewrite that page anyway. Feel free to change it!
