Hi @michelweb, that URL doesn't seem to be working so I am not sure what exactly you're asking, Can you elaborate a bit?

The external server where i hosted the pic seems to be down ... Silly i am, i didn't thought to host it on my own domain. I hosted it on my domain name : https://cine-phil.fr/auth.png

So Is it possible to replace the TMDB page by my own page (keeping only the 2 buttons for the approve or the deny) ? Thanks

Heh, it happens.

Ok, so to answer your question, no, it is not possible to replace that page. You are authenticating a TMDB user, and that can only happen on TMDB.
