What are the disadvantages to security question?

Security questions can be easily guessed or researched, especially if the answers are publicly available or easily deduced from social media. Additionally, users may forget the answers to their security questions, leading to access issues. This method also lacks the robustness of more secure authentication methods, such as multi-factor authentication, making accounts more vulnerable to unauthorized access. Lastly, relying on security questions can create a false sense of security, as they may not provide adequate protection against sophisticated attacks.
