• Question selection: Select a question you can answer easily but that will be difficult for others to guess. Treat your secret question like any other confidential information - don't share it.
• Types of answers: For security purposes, you might try using an incorrect or irrelevant answer to the question. For example: If your secret question is "What is your favorite food?" you might choose "spinach" for your answer - actually your least favorite food.
• Difficult to guess and stable: Make sure that your security question cannot be easily guessed, doesn't change over time, and is simple to remember.

Good security questions have four common characteristics. The answer to a good security question:

1. Cannot be easily guessed or researched (safe),
2. Does not change over time (stable),
3. Is memorable,
4. Is definitive or simple.
