Definition
The term, in context
AI-assisted draft · approved dataset
Yubico YubiKey 5.8 is a firmware revision of a hardware security key that implements CTAP 2.3 alongside asynchronous remote key generation, a scheme in which further public keys can be derived for the key while the key itself is offline. Those derived keys let a service or credential manager enrol additional credentials bound to a hardware authenticator kept in safe storage, so a backup key does not have to be plugged in for every registration.
