What capability allows customers to manage their own contact details in self-service?

The capability that enables customers to manage their own contact details in a self-service environment is updating account passwords. When customers have the ability to update their account passwords, it is often part of a broader self-service functionality that includes managing other account settings, such as contact information.

Self-service portals typically allow users to access their profiles, where they can review and edit personal details, ensuring that their information, such as phone numbers and email addresses, is current. The ease of updating passwords alongside personal details enhances user autonomy and ensures that customers can maintain the security and accuracy of their information without needing to contact support staff directly.

This capability is essential for improving customer experience, as it reduces the need for assistance from support personnel for routine account management tasks. In contrast, the other options listed do not directly pertain to managing contact details; instead, they involve different aspects of customer interaction with support services, such as making appointments, submitting requests, or checking system statuses.
