For Your Security
For your security, we may ask you these security questions to verify your identity.
Security questions don't make me feel more secure. Many times, the answers are either a simple Google search away, or they don't even apply to me (although I wish I did have an older sibling and that they had a charming nickname). Most of the time, I'll forget what I entered, if the answers are case-sensitive, and who exactly was my favorite pet.
I'm sure there's research that supports using security questions. I'm sure that security questions can improve internal KPI's around compromised accounts and show that support time spent goes down when they are used. But they don't make me feel more secure.
