Description: Overlay authentication is an authentication method that adds an extra layer of security over existing systems. This approach is based on the idea that, in addition to traditional credentials like passwords, additional mechanisms are implemented that require the verification of multiple factors before granting access to a system. These factors can include something the user knows (like a password), something the user has (like a token or mobile device), and something the user is (like a fingerprint or facial recognition). Overlay authentication is especially relevant in a context where cyber threats are becoming increasingly sophisticated, as it provides a more robust defense against unauthorized access. By combining different authentication methods, the risk of an attacker compromising an account is significantly reduced, even if they manage to obtain one of the credentials. This approach not only enhances security but can also increase user trust in the system, knowing that additional measures are being taken to protect their personal information and sensitive data.
