So I have this site running under ssl (on siteground).

The site is new, the instalation has no more than 2 weeks.

I have a working desktop app to connect to my sites, using jwt tokens, but the plugins for this token are old and has not being tested with newer WP versions. So to keep everything up to date, I want to change to this kind of auth.

But when I try my site, using get over the rest-api, I don´t get the authentication key according to this.

So I think that app passwords are not enable by default.

If that is the case, according to that page, I have to add:

add_filter( 'wp_is_application_passwords_available', '__return_true' );

somewhere, but I don´t know where to add it.

Or is this something else I have to be cheking?
