VR Developers, don’t use the Meta XR SDK to develop your games. Whether you use Unity or Unreal, you should use the built-in OpenXR support in the engines. The Meta XR SDK only works with Quest & Link; it is a buggy mess hardcoded to not work with other runtimes and headsets.

@github thanks for github.com/github/webauthn-j… ! Unfortunately, it’s still very useful, as MacOS Safari 18.6 likes to crash the tab when toJSON is called :(
FYI to @KyFaSt in case this is a factor in the recent archival decision. In particular, have a credential for a resident key from iCloud Keychain with prf extension, Apple always crashes. Not looking for support, just an FYI that it’s still useful :)

Activision always email you backup codes when you activate 2FA… so if your email gets compromised, your Activision account is compromised. What was the point of 2FA again?
“Login with code send to my email” instead of password + 2FA would be just as secure with fewer steps
2/3. More than half of the headsets on the Steam Hardware Survey are Quest-series headsets that have support for hand tracking, but it requires developer mode or third-party software.
