You could create a single user called anonymous and auth that user to get a generic token.

There is an open issue for a more elegant solution; feel free to upvote it: https://github.com/FusionAuth/fusionauth-issues/issues/525

We don't support this currently. If you have a use case that this would be helpful for, please file a GitHub issue explaining what you are looking for.

It is sorta possible to create a user with a randomly generated email and password. So if you wanted to allow people to sign up, you could generate this user, and then send them/present login details, and then the user could be anonymous but still have a profile.
