Authentication for files now required?
The page https://developer.themoviedb.org/docs/daily-id-exports
says that currently no authentication would be required to access these files.

Yes.
Authentication is not required. You do not need to use an API Key or TOKEN.

However, if I try to access them here https://files.tmdb.org/, I get an authentication error.

You cannot access the root directory of the files.
You can only download the files.

Then I created this account but I'm still unable to access them.
What else is required?
Do I need an API key although I don't want to access the API?

Just create the URL of each file with the date in the correct format.
MM_DD_YYYY
The possible files are listed on the page.
https://developer.themoviedb.org/docs/daily-id-exports
There is also the time of day that they are made available.
I believe that they are available for a maximum of 90 days.

For example, for movies:

http://files.tmdb.org/p/exports/movie_ids_01_29_2025.json.gz  

Thanks, that works. It's a bit weird, that they put a clickable link into the document and expect users to not click it and understand that the link is useless :D I was able to download the file and view it. Unfortunately they are completely useless because they don't include any regional title names.
