Security questions are a method used to verify a person's identity, often during account recovery or login processes. Users are asked to answer specific questions that only they should know, such as the name of their first pet or their mother's maiden name. This adds an extra layer of protection against unauthorized access. While security questions can enhance account security, they can also pose risks if the answers are easily guessable or publicly available. It's important for users to choose questions and answers that are unique and not easily found through social media or other sources to maintain their online security.
