Security Keys

Security keys are physical devices that are used to securely authenticate a user or device. They provide a more secure form of authentication than traditional username and password combinations and can be used to protect sensitive information, such as online accounts and sensitive data.

Security keys work by using public key cryptography to verify the identity of the user or device. When a user attempts to log in to an account, they insert their security key into their device and press a button to complete the authentication process. The security key then communicates with the service provider to verify the user's identity.

Security keys are considered to be more secure than traditional passwords because they provide a stronger form of two-factor authentication. Unlike passwords, which can be easily guessed, lost, or stolen, security keys are designed to be tamper-resistant and are much harder to duplicate or steal.

There are several different types of security keys, including USB security keys, NFC security keys, and smartcard security keys. Some security keys can also be integrated into a user's mobile device, providing a more convenient form of authentication.

By using security keys, organizations can help to prevent unauthorized access to their systems and protect sensitive information from theft and other security threats. They are also a recommended method for meeting the requirements of various security standards, such as the Payment Card Industry Data Security Standard (PCI DSS).
