Questions and Answers policy consists of secret questions and Q&A profile settings. Secret questions are questions that users must answer to create their profiles and then use the profiles for authentication. You can create question lists in multiple languages. Each question list contains mandatory, optional, and helpdesk questions. When creating profiles, users must answer all mandatory and helpdesk questions, and a specified number of optional and user-defined questions. You can specify the required number of question in the Q&A profile settings.
When authenticating on the Self-Service site with Q&A profiles, users can use mandatory, optional and user-defined questions from their profiles. When a helpdesk operator authenticates users, the operator can use mandatory and helpdesk questions from users’ profiles.
Q&A profile settings are a collection of settings that define the number of user-defined and optional questions required for registration, minimum length of answers, encryption setting for storing answers, and others.
When you configure the Q&A policy, you should remember that the settings you specify may affect the authentication process. The following authentication activities use the Q&A policy settings:
This activity uses mandatory and helpdesk questions. Helpdesk questions are always stored using reversible encryption. Mandatory questions are hashed, unless you select the Store answers using reversible encryption option in the Q&A profile settings. Note, that if mandatory questions are hashed, you will not be able to use the activity option that specifies that helpdesk operators verify user identity by comparing the answers provided by users with the displayed answers (the Answers to the specified questions (user’s answer is shown) option). For more information, see Authenticate with Q&A Profile.
The Q&A profile settings affects the Invite users to create/update Q&A profiles enforcement rule. This rule has conditions that state when users should be notified to create or update their profiles. These conditions correspond to the Q&A profile settings. For example, the User’s answers are shorter than required condition corresponds to the Minimum length of answers setting. So, when you change any of the Q&A profile settings, you can then select the corresponding condition in the rule and enforce users to create or update their profiles in accordance with the new settings. For more information, see Invite Users to Create/Update Profiles.
