users

In technology, a user is an individual or organization that interacts with a product or service to achieve a goal. Users may access software applications, websites, cloud services, devices, or embedded systems, and their needs shape how the product is designed and evaluated.

Users can be categorized by role and access level. End users are the primary operators who interact with the system to complete tasks. Administrators manage configuration, permissions, and maintenance. Other common categories include casual or power users, guests, and registered or authenticated users, depending on the product's access model.

Understanding users involves user research, usability testing, and modeling techniques such as personas and user journeys. Designers seek to align interfaces with users' tasks, contexts, and limits, and to ensure accessibility for people with disabilities.

Security and privacy considerations govern how users authenticate, authorize actions, and control data. Practices include least-privilege access, consent management, data minimization, and compliance with privacy regulations. Accessibility and inclusive design also ensure a broader range of users can interact with the product.

User lifecycle concepts cover onboarding, account maintenance, updates, and eventual deactivation or deletion. Products may support data portability and user-generated content, reinforcing user rights and transparency in terms of service. The recurring goal is to enable reliable, respectful, and usable experiences for all users.
