Definition
A security question asks for personal knowledge (pet name, school) as an account recovery or extra check — often weak because answers can be guessed or researched.
Real-World Example
Using your mother’s maiden name as a recovery question is risky if that detail appears on genealogy sites; prefer app-based 2FA instead.
