  FIDO2 authenticators can enhance the security of cryptocurrency wallets in several ways. Firstly, they provide an additional layer of protection by requiring a physical device, such as a USB key or a biometric scanner, to authenticate transactions. This means that even if someone gains unauthorized access to your wallet's password, they won't be able to access your funds without the physical device. Secondly, FIDO2 authenticators use public-key cryptography, which ensures that the private keys used to sign transactions are never exposed to the internet. This significantly reduces the risk of key theft or unauthorized access. Lastly, FIDO2 authenticators support multi-factor authentication, allowing users to combine different authentication methods, such as a password and a fingerprint scan, for added security.
