# Delete KBA question and answer pairs

This procedure explains how to delete one or more question-and-answer (Q&A) pairs from a knowledge-based authenticator (KBA). Before you begin, note the following:

- In the User Portal, only the user can modify their KBA answers.
- Every user must keep a minimum number of Q&A pairs. A user cannot delete a Q&A pair if doing so would reduce the total below the required minimum.
- The minimum number of Q&A pairs is based on the configured KBA challenge settings. For more information, see [Modify knowledge-based authenticator settings](/docs/authentication-and-security/manage-authenticators/manage-knowledge-based-authenticators-kba/modify-kba-settings.md).

2. The user still has enough Q&A pairs to satisfy the minimum challenge requirements.
3. The user can still complete KBA authentication with the remaining questions.
