I’m still not seeing how this solves the issue. You either use Cloudflare or your reverse proxy as the auth, which is secure but then people can only use your Jellyfin server through a web browser, or you publish actual Jellyfin and use its auth, but now you rely on its poor security.
Are you saying you integrate fail to ban with Jellyfin’s auth? If so that’s alright, but won’t stop anyone from using an exploit, just brute force attacks. I’m still also not sure why the VPS is required at all.

Considering the thread we’re talking in, it’s up to you if you trust MS to implement this well, but they are not uploading the screenshots to the cloud.
Personally I think the idea of Recall is great if it works to help you and only you. The problem isn’t the idea, it’s the trust. If a reputable open source project or Linux distro made a feature like this I think it would be cool, because I know my privacy is going to be respected and the feature is designed solely to help me and nothing more. However, when MS suggests this I’m immediately cautious, skeptical, and concerned about how it could be used against me.
