Which is the supper user "token_auth"?

I want to add user via http, But it need the supper user’s token_auth.
how can I get it.

Log in as administrator, go to the settings - user page.
In the user list, you can see each user’s token_auth.

As for the super user, I don’t think it has one.
It’s settings are in config.ini.php:

[superuser]
login = ""
password = ""
email = ""
salt = “”

There is no token_auth key for the superuser in the database either.
(The entire superuser is not part of the data in the database. see config/config.ini.php)
