Can calibre-web use passkey authentication?

I want to expose my ebook collection with self hosted calibre-web. I wonder if I can add passkey authentication to it. Is it naively available in calibre-web? Is there a way I could add it easily?

That would be a question for the devs of calibre-web, but i am unaware of any passkey support. Calibre-web does support passthru authentication via headers though, I use authelia (and in the past, authentik) to allow logins with MFA. You could look into these to see if they support passkeys.
