Description: Re-authentication is the process of verifying a user’s identity again after they have completed the initial authentication. This procedure is especially critical in environments where sensitive data is handled or actions that may compromise system security are performed. Re-authentication is used to ensure that the person attempting to access information or perform a specific action is indeed who they claim to be, thereby minimizing the risk of unauthorized access. This process may involve entering additional credentials, such as a code sent to a mobile device or answering security questions. Re-authentication is an essential component of multifactor authentication (MFA), which combines different verification methods to enhance security. In a world where cyber threats are becoming increasingly sophisticated, re-authentication has become a standard practice in various applications and services, ensuring that only legitimate users can access critical information or perform important transactions.
