In r/AskNetsec, the community frames passkeys and YubiKeys as complementary controls, emphasizing that account recovery and the vault protecting synced passkeys are the real takeover risk, so stacking factors is safer.
Yes, still worth it. Passkeys and YubiKeys are not competing controls, they stack.
A YubiKey can be the thing that stores or unlocks your passkeys, or the strong MFA/recovery factor for the account that syncs them.
If your passkeys live in iCloud Keychain, Google Password Manager, or 1Password, the real question is: what protects that vault and its recovery flow?
Passkey. You are fked if you lose the device. You are fked if you lose access to the platform holding it e.g. Apple, Google, 1Password.
Why not use both? Passkey for day to day and Yubikey for emergency?
