Understanding Security Keys
A security key is a physical device utilized for two-factor authentication (2FA) or multifactor authentication (MFA). It offers an added layer of security by requiring not only your password but also a physical key—something you have—making unauthorized access significantly harder for cybercriminals.
Security keys are essential in protecting sensitive information stored on your laptop and other devices, guarding against various threats like phishing attacks, credential theft, and unauthorized access. Let’s break down the main aspects of security keys:
How Do Security Keys Work?
Security keys work by producing a cryptographic signature that verifies your identity when accessing your laptop or online accounts. Here’s a simple breakdown of how the process typically works:
Registration: When you first set up your security key, it is registered with the online service or your laptop. During this process, the service generates a public key and a private key.
Authentication: When you try to log in, the service sends a challenge to your laptop, prompting it to activate the security key.
Response: The security key uses its private key to create a response based on the challenge sent by the service. This response is then sent back to the service for verification.
Access granted: If the response is valid, access is granted to your account or device.
This system ensures that even if an attacker has your password, they cannot log in without the physical security key, thereby significantly enhancing security.
