How does strong authentication work?

Strong authentication works by requiring users to provide two or more forms of identification in order to access a system, application, or service. The authentication process typically involves the following steps:
The user attempts to log in to the system or application by providing a username and password, which is the first factor of authentication (something you know).

The system or application then prompts the user to provide additional forms of identification, such as a security token, biometric data, or a code sent to their mobile device, which serves as the second factor of authentication (something you have or something you are).

Once the user has provided the required additional factor(s), the system or application verifies the user's identity and grants access if the authentication is successful.

The specific process and technologies used in strong authentication can vary depending on the system or application being accessed. For example, some systems may use a mobile app or hardware token to generate a one-time code that must be entered as the second factor, while others may use biometric data like fingerprints or facial recognition.

Overall, strong authentication provides an additional layer of security beyond a simple username and password, making it more difficult for attackers to gain unauthorized access to sensitive systems and data.
