Which feature allows customizing accessibility in Qualtrics?

The feature that allows customizing accessibility in Qualtrics is the Authenticator. This tool is primarily designed to manage user access and ensure that the appropriate respondents gain entry to your survey while maintaining security and confidentiality. By customizing the authentication process, you can accommodate individuals with different accessibility needs, ensuring that they have an equitable experience when interacting with your survey.

For instance, the Authenticator can provide options for password protection or other methods that might be tailored to different user requirements, thus enhancing the accessibility of your survey experience.

The other options, while useful in various contexts, do not specifically address customizing accessibility. The Randomizer is primarily used for showing different sets of survey elements randomly to participants, aiding in experimental design. The Filter allows you to control the flow of participants based on their responses but does not specifically enhance accessibility for users. The Table of Contents provides navigation options for long surveys but does not directly influence accessibility features.
