Using public key cryptography, it is possible to prove possession of a private key without revealing that key. The authentication server encrypts a challenge (typically a random number, or at least data with some random parts) with a public key; the device proves it possesses a copy of the matching private key by providing the decrypted challenge.
The underlying cryptographic operations are performed by an authenticator, which is an abstract functional model that is mostly agnostic with respect to how the key material is managed. This makes it possible to implement support for WebAuthn purely in software, making use of a processor's trusted execution environment or a Trusted Platform ...
The RSA SecurID authentication mechanism consists of a "token"—either hardware (e.g. a key fob) or software (a soft token)—which is assigned to a computer user and which creates an authentication code at fixed intervals (usually 60 seconds) using a built-in clock and the card's factory-encoded almost random key (known as the

In 2020, independent security researchers found a method to extract private keys from Google Titan Key, a popular U2F hardware security token. [12] [13] [14] The method required physical access to the key for several hours, several thousand euros-worth of equipment, and was destructive to the plastic case of the key.
