Step-up authentication is a process where users are prompted to provide additional verification when accessing sensitive operations or data. This method enhances security by requiring more stringent authentication measures for high-risk actions, reducing the likelihood of unauthorized access. What is step-up authentication? Step-up authentication is a security mechanism that increases the level of authentication required for sensitive operations. It typically involves asking users to provide additional verification, such as multi-factor authentication (MFA), before granting access to critical systems or data. Why use step-up authentication? Using step-up authentication helps protect sensitive operations by ensuring that only authorized users can perform high-risk actions. It adds an extra layer of security, making it harder for attackers to gain unauthorized access, even if they have compromised a user's primary credentials. How does step-up authentication work?…
