How do FIDO2 security keys work?
Security: FIDO2 encrypts the login by default with a pair of keys (private and public) that can only be unlocked with the registered device. The cryptographic login credentials are unique for each website. Besides, they never leave the user's device and they are not stored on any server.
There are a lot of advantages to FIDO2, primarily around security, convenience, privacy, and scalability. FIDO2 does not store credentials on a server and uses unique cryptographic login credentials, which helps reduce the likelihood of phishing, password theft, and replay attacks.
FIDO2 advantages
Replaces weak passwords with strong hardware-based authentication using public key crypto to protect against phishing, session hijacking, man-in-the-middle, and malware attacks. No secrets are shared between services.
FIDO2 enables users to leverage common devices to easily authenticate to online services in both mobile and desktop environments. The FIDO2 specifications are the World Wide Web Consortium's (W3C) Web Authentication (WebAuthn) specification and FIDO Alliance's corresponding Client-to-Authenticator Protocol (CTAP).
The private key is stored securely on the device and can only be used after it has been unlocked using a local gesture like biometric or PIN. Note that your biometric or PIN never leaves the device. At the same time the private key is stored, the public key is sent to Azure AD and registered with your user account.
What is a FIDO security key? Fast Identity Online (FIDO) is a technical specification for online user identity authentication. It is used in scenarios such as fingerprint login and two-factor login, allowing you to use biological features or a FIDO security key to log in to your online accounts.
FIDO2 authentication enables users to capitalize on common devices to authenticate quickly and securely to online services in both desktop and mobile environments. FIDO authentication is the industry's solution to the global password challenge and addresses all of the concerns of traditional authentication.

Each key has a built-in fingerprint reader, so you can log in with the tap of a finger instead of having to remember your password. The key could also serve as a form of two-factor authentication.
What services use FIDO2?
The Winkeo-C FIDO2 from Neowave is a compact little security key that also supports the older FIDO U2F specification that works with AWS, Dropbox, Facebook, GitHub, Gmail, GOV.UK, Okta, Salesforce, Twitter, Zoho and dozens of other sites and services.
A properly implemented Yubikey cannot be cloned. It can be stolen, but ideally you would notice it was missing. An authenticator can be copy/cloned. One can debate the difficulties involved but the end result is that the authenticator can be stolen but it would not be missing.
These FIDO2 security keys are typically USB devices, but could also use Bluetooth or NFC. With a hardware device that handles the authentication, the security of an account is increased as there's no password that could be exposed or guessed.
Each Security Key model fits either a USB-A or USB-C port, and most phones support NFC, so the keys should work fine for most devices. Get whichever key fits into the port on your computer.
With FIDO2, there is no need to replace passwords, as there are no passwords required. For those combining a hardware authenticator with a PIN, it's important to note that PINs do not demand the same security requirement as a password.
FIDO2 enables more methods of authentication to be verified by a single key. Combining certificates with Security Keys is a great way to ensure strong security.

Security keys are cheap, easy to use, put an end to phishing attacks, and are less hassle and much more secure than SMS-based two-factor authentication.
What can FIDO2 help with? Implemented properly, public-key cryptography makes phishing or man-in-the-middle attacks virtually impossible. These attacks rely on gaining access to a shared secret (such as a password or OTP) – but as FIDO2 protocols do not transmit the private key, there is no shared secret to access.
Keep your eye on your security key, unless it has some sort of strong biometric or other lockout to prevent other people using it. If someone can steal your key for long enough to clone it using this attack, they can probably access your account anyway without cloning the key.
The Supra C500 key safe is hard to beat. It is one of the most secure key safes available today. The Supra C500 has received an independent security rating (LPS1175 Level 1 Accreditation) which means it provides as much security as a domestic front door.

What is the difference between YubiKey and security key?
But the security protocol for the Security Key and the Yubikey 5 NFC are the same, so it's not that the other keys are “less secure”, it just means that they don't offer that additional layer of security. It's really the difference between 2FA and MFA.
Resident keys in FIDO2 are used for password-less + username-less authentication, which is kind of a special case. With "regular" I was referring to the "regular" (lol) case of two-factor authentication, either with u2f or fido2.
True security keys are 'Patent Protected' and will have this embossed on the key itself, with the words 'Do Not Duplicate' - they need both to be true!
