On March 13, we will officially begin rolling out our initiative to require all developers who contribute code on GitHub.com to enable one or more forms of two-factor authentication (2FA) by the end of 2023. Read on to learn about what the process entails and how you can help secure the software supply chain with 2FA.
If your account is frozen they should still be on the device. That would be a good time to change all your passkeys over to a yubikey, or to add one as a secondary token.
The keys being locked in a Secure Enclave is generally considered a feature, not a bug. That passkeys sync at all is somewhat concerning. I wouldn’t expect them to be exportable any time soon.
The use of a “secure enclave” for any purpose is a bug at best, because secure enclaves aren’t just secure against your adversaries; they’re also secure against you. This is intolerable. All machines must obey their owner.
The Secure Enclave can apparently return the private key. For most keys it is encrypted with a key pair that is permanently stored in the Secure Enclave. For synchronized keys it is apparently encrypted with a key that is also stored in iCloud in such a way that Apple themselves cannot get to it.

Hard disagree. That rules out yubikey, smart cards, and most any other credential storage systems.

Apple actually describes the process for sync in some detail: https://support.apple.com/guide/security/secure-keychain-syncing-sec0a319b35f/web
Apple also describes the keychain recovery process in depth (I think this is when you’ve lost all devices?): https://support.apple.com/guide/security/escrow-security-for-icloud-keychain-sec3e341e75d/1/web/1
