FIDO2 security keys are very important because they help organizations achieve a passwordless environment much faster due to their interoperability and security design. They work right out of the box and use a separate cryptography chip to qualify for the highest authenticator assurance level, thereby making it possible to meet the most rigorous compliance requirements.
How does Fido2 key work? When a person registers the FIDO2 device at an account at a particular website, the device creates a new key pair that is usable only at this website and gives the website the public key to associate with the account. When the user authenticates, or logs in, to the website, in addition to username and password, the website checks whether the user has the FIDO2 device or not by verifying the key that was specifically created for this website (the signature created by the device). Remember that the user can authenticate with just the username if the website only wants a FIDO2 device verification
Multifactor authentication Fido2 key requires an additional fingerprint verification on the token to prove that the key holder identity has an optimum security level. Fido2 keys are not limited to a single website. They can be used across multiple sites on the web.
There are various advantages of using FIDO2 keys. One of them is that they provide strong security. It uses strongtwo-factor and multi-factor authentication using public key crypto that diminish malware attacks, hijacking, phishing, and man-in-the-middle attacks.
A FIDO2 key is also ease to use. The simple user interface and instant authentication when plugged in or button pressed make it so easy to use.
You will also appreciate the high privacy of the FIDO2 keys. They allow users to choose, own, and control their online identity with no personal information shared to the services except for the specially created key that associates the user identity with the service.
