X25519Kyber768 is an IETF Internet Draft designed to bring post-quantum asymmetric cryptography to TLS. It has already been implemented in Chrome, Edge and Firefox for a while but since version 124 it's enabled by default in Chrome and Edge.

Chromium feature link which includes deployment plan Cloudflare Research site dedicated to post-quantum cryptography IETF draft status

I made some tests on Browserstack and it seems like it's also behind a flag starting from Opera 101. It's supported but not enabled by default on Chrome, Android. There's no mention of support on Apple platforms nor any other less-popular independent browsers.

Closes #7072.
