What is a Security Question?

A security question is a method of authentication used by online services and websites to verify the identity of a user during the account recovery process. When a user forgets their password or encounters difficulty accessing their account, they may be prompted to answer a security question to prove their identity. Typically, during the account creation or setup process, users are asked to choose a security question and provide an answer. Common security questions might inquire about personal information, such as the user's first pet's name, mother's maiden name, or the city where they were born.

What is a Security Question

The idea is that the answers to these questions are known only to the legitimate account owner, adding layer of security when trying to regain access to an account. However, security questions have faced criticism for being vulnerable to social engineering attacks, as some information may be publicly available or easily guessed. As a result, some online services are moving towards more secure methods of account recovery, such as two-factor authentication or recovery codes. These questions typically ask for personal information that, ideally, only the account owner should know. However, as mentioned earlier, the use of security questions has been criticized for being potentially insecure, as some answers can be easily obtained or guessed. It's often recommended to use alternative methods of authentication, such as two-factor authentication, to enhance account security.

Security questions are a form of authentication that has been commonly used by online services to verify the identity of users during account recovery processes. The primary purpose is to provide a secondary means of access in case a user forgets their password or encounters difficulties logging into their account. However, it's essential to note that the effectiveness of security questions has been debated, and some experts argue that they may introduce security vulnerabilities.

Examples of Security Questions

  • What is your mother's maiden name?
  • In what city were you born?
  • What is the name of your first pet?
  • What is your favourite book/movie/band?
  • What is your favourite colour?
  • Where was your favourite vacation destination?
  • What is the make and model of your first car?
  • What was the name of your best childhood friend?
  • What is the name of the street you grew up on?

Choosing Strong Security Questions

  • Users are typically prompted to choose security questions and provide answers during the account setup process.
  • It's advisable to select questions with answers that are not easily guessable or publicly available information.
  • Avoid questions with answers that can change over time, as this might lead to confusion during the account recovery process.

Purpose of Security Questions

Account Recovery: Security questions serve as a secondary authentication method primarily for account recovery purposes. When users forget their passwords or lose access to their accounts, correctly answering these questions can help them regain entry.

Additional Layer of Security: Security questions are designed to add an extra layer of security beyond just a password. By requiring knowledge of specific personal information, they aim to ensure that the person attempting to recover the account is the legitimate owner.

Protecting Against Unauthorized Access: Security questions are intended to thwart unauthorized access to user accounts by ensuring that only the legitimate account owner, who presumably knows the answers to the selected questions, can initiate the account recovery process.

Enhancing Account Security: While not foolproof, security questions are designed to strengthen overall account security by introducing an extra step beyond password protection. This is especially important in cases where users may forget their passwords or encounter situations necessitating account recovery.

User Verification: Security questions are a way for online services to verify the identity of users, particularly when the standard login credentials are unavailable or forgotten. This process helps prevent unauthorized individuals from posing as the account owner.

Note: While security questions have been widely used, they are not without criticism. Issues such as predictability, guessability, and the potential availability of personal information have raised concerns about their effectiveness. As a result, some online services are exploring more advanced authentication methods, such as biometrics and two-factor authentication, to further enhance security.

User Education regarding Security Questions:

  • Users should be educated about the importance of strong, unique passwords and the potential risks associated with security questions.
  • Encouraging users to enable additional security features, like 2FA can enhance the overall security of their accounts.
  • Users are encouraged to select questions with answers that are not easily guessable and to avoid commonly known or easily researched information.
  • Some platforms recommend users periodically update their security questions or review and modify their account recovery settings.
  • Educating users about the potential risks associated with security questions, especially in the context of oversharing personal information online.

Advantages of Security Questions

While security questions have been a common method for account recovery and additional authentication, it's essential to note that they come with both advantages and disadvantages. Here are some advantages of using security questions:

  • Security questions provide a relatively user-friendly method for account recovery. Users can regain access to their accounts without the need for external devices or complex procedures.
  • Unlike two-factor authentication that often requires a secondary device, security questions can be answered without the need for any additional hardware or software, making them accessible to users with basic devices.
  • Security questions allow users to personalize their account security by selecting questions that are relevant and memorable to them. This customization can enhance the overall user experience.
  • Implementing security questions is generally straightforward and comes with a low cost compared to more advanced authentication methods. This simplicity can make it an attractive option for smaller or less resource-intensive platforms.
  • Security questions introduce an additional layer of security, acting as a barrier against unauthorized access. While not infallible, they can deter casual attempts to compromise an account.
  • Security questions have been a longstanding and widely used practice in the industry. Many users are familiar with this method, making it a convenient and accepted approach for account recovery.
  • In situations where other authentication methods fail or are unavailable, security questions can serve as a fallback option for users to regain access to their accounts.

While these advantages exist, it's essential to balance them with the potential drawbacks of security questions, such as the risk of predictability, the static nature of the information, and the increasing prevalence of more secure authentication methods like two-factor authentication. The effectiveness of security questions depends on the implementation and the specific security needs of the platform or service.

Concerns and Criticisms of Security Questions

  • Some security questions rely on information that might be publicly available or easily guessable, especially with the prevalence of social media.
  • Answers to static security questions (like birthplaces or mother's maiden names) remain constant, potentially posing a security risk if obtained by malicious actors.
  • Security questions, when used alone, may not provide sufficient security. They are often criticized for being less secure compared to other methods like two-factor authentication.
  • Security questions are not foolproof, as some answers can be obtained through social engineering or by researching an individual's online presence.
  • Personal information, such as birthplaces or mother's maiden names, might be discoverable through social media or other public records, making it easier for malicious actors to gain unauthorized access.

Alternatives and Evolving Practices

  • Two-Factor Authentication (2FA): Many services are moving towards more secure methods like 2FA, where users need to provide a second form of verification, often through a mobile device or authentication app.
  • Recovery Codes and Email Verification: Instead of relying solely on security questions, some platforms use recovery codes or send verification emails to registered addresses for account recovery.
  • Behavioral Biometrics and Advanced Technologies: Emerging technologies, such as behavioral biometrics or device recognition, aim to provide more dynamic and sophisticated means of authentication.
  • Dynamic Security Measures: Some platforms are exploring more dynamic security measures, such as behavioral biometrics or device recognition, to continuously assess the legitimacy of access attempts.


In conclusion, security questions have played a longstanding role in online authentication, primarily serving as a means for users to recover access to their accounts. Despite their advantages in user-friendliness, accessibility, and low implementation costs, security questions face significant criticisms and challenges. The static nature of personal information used in security questions poses a risk, as answers can be predictable, easily guessable, or even publicly available. This vulnerability undermines their effectiveness as a robust security measure. Furthermore, the evolving landscape of cybersecurity has prompted a shift toward more advanced and secure authentication methods, such as two-factor authentication and biometrics.
