largeBlob support in passkeys?

Apologies if this is not the right forum for this type of question. But I'm working on a website that will use passkeys for authentication. Additionally, I'm trying to use the https://developer.mozil...

Sure! What I'm trying to do is simplify management (and sync) of E2E encryption keys. So when you sign up for an account, you register a passkey, and your browser uses its https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto to generate a couple keypairs (for signing and key exchange). I send the public keys to the server, and store the private keys alongside the passkey (using the largeBlob extension). It's totally transparent to the user, the private keys never touch my server, and it syncs to all their devices automatically - no scanning QR codes or implementing my own key wrapping/syncing mechanism.

Thanks so much for the response - a feature request would be lovely! And let me know if you'd like any more information.

Thanks,
Dan
