Description: The security key is a small hardware device used for authentication, providing an additional layer of security in accessing systems and data. This device can take various forms, such as a USB keychain or a physical token, generating unique access codes or storing cryptographic keys necessary to verify the user’s identity. Its main feature is that it requires the physical presence of the user to complete the authentication process, making unauthorized access difficult even if an attacker has the user’s password. Security keys are especially valued in environments where the protection of sensitive data is critical, such as in businesses and governmental organizations. Additionally, their use has expanded with the growing concern for cybersecurity, becoming an essential tool for protecting online accounts and computer systems. In the context of technology, these keys can be integrated as part of a broader security approach, which includes multifactor authentication and protection against advanced threats.
History: Security keys have their roots in the evolution of authentication and cryptography. In the 1980s, the first hardware authentication devices, such as RSA tokens, began to appear, offering a form of two-factor authentication. Over time, technology has advanced, and in 2014, the FIDO Alliance introduced the U2F (Universal 2nd Factor) standard, which enabled the creation of more accessible security keys compatible with multiple online services. This advancement marked a milestone in digital security, promoting the adoption of security keys across various platforms.
Uses: Security keys are primarily used for two-factor authentication (2FA) across various online applications and services. They allow users to access email accounts, social media, and banking platforms more securely. Additionally, they are used in corporate environments to protect access to critical systems and sensitive data, ensuring that only authorized users can access the information. They are also used in mobile devices and computers to enhance the overall security of the system.
Examples: An example of using a security key is accessing online accounts, where users can use a USB security key to verify their identity when logging in. Another case is the use of security keys in organizations that require secure access to their internal networks, where employees must present their security key to access confidential information. Additionally, some cryptocurrency platforms allow the use of security keys to protect user accounts against unauthorized access.
