Using this feature, you can secure the 'Security Q & A' process which serves for the purpose of user authentication. This feature offers you with a "set of self-explanatory rules" which can be imposed onto the user - in order to maintain the confidentiality of the user account - while he undertakes the Security Q & A process.
The rules under this feature are listed below:
Prevent a user from providing the same answer to multiple questions
Prevent a user from using any word of a question in their answers
Display security questions one by one
Display only a random subset from a user's security questions
Make security answers case-sensitive
Hide answers during reset/unlock operations
