Manage knowledge-based authenticators
Knowledge-based authentication (KBA) allows you to authenticate by answering one or more questions. Identity as a Service provides a default, system-defined list of questions. Depending on how your administrator has configured KBA, you must answer a minimum number of questions. The personalized answers ensure that only you are likely to respond correctly. Your answers are stored in encrypted form in a repository.
KBA can be used to complete first-factor authentication challenges when logging in to Identity as a Service. Depending on how your account resource rules are configured, you can also use it to complete first or second-factor authentication challenges to SAML applications.
Choose one of these procedures, as required.

You can only add one knowledge-based authenticator (KBA) to your account. When you answer a question, the question becomes available to you as an option during a KBA challenge. Unanswered questions are not included in KBA challenges. If you want to start over after saving your KBA, you must first delete the existing one before you can add a new one.
Complete the following procedure to add a KBA to your list of authenticators.
