What is the main purpose of a cognitive password?

To provide multi-factor authentication
To verify user identity through knowledge
To encrypt user credentials
To create a digital footprint

The correct answer is: To verify user identity through knowledge

A cognitive password primarily serves the function of verifying user identity through knowledge. This type of password relies on information that is unique and familiar to the user, such as answers to personal questions or details about experiences that are not easily guessed or obtained by others. This method leverages the concept that the individual has knowledge that only they would possess, thus strengthening the authentication process. Cognitive passwords differ from traditional passwords in that they can include questions about memorable events or personal details that are less likely to be shared, making them more effective in confirming identities. They help mitigate unauthorized access by ensuring that only those with the requisite knowledge can gain entry, emphasizing the role of knowledge in identity verification.
