hardwarenøglen

A hardwarenøgle, often referred to as a hardware key or security token, is a physical device used to authenticate access to computer systems or online accounts. It typically connects to a computer via a USB port or wirelessly through technologies like Bluetooth or NFC. The primary function of a hardwarenøgle is to provide a strong form of multi-factor authentication (MFA), adding an extra layer of security beyond just a password.

When a user attempts to log in, the hardwarenøgle generates a unique, one-time code or cryptographic key that is then transmitted to the authentication system. This process ensures that even if a password is compromised, an unauthorized individual cannot gain access without possessing the physical hardwarenøgle. Common examples of hardwarenøgler include YubiKeys, Google Titan Security Keys, and various smart card readers. They are widely used by individuals and organizations to protect sensitive data and critical infrastructure from cyber threats. The use of hardwarenøgler significantly reduces the risk of account takeovers and phishing attacks.
