Prismatic has introduced a new authentication model called "connections" to enhance the integration development experience by providing more flexibility, better deployment experiences, and improved support insights. This new system allows developers to define custom authentication types, simplifying the process by combining related credentials and configuration variables into single connection variables, which improves the user experience for both developers and customers. Connections also streamline the OAuth 2.0 process, allowing customers to authenticate with third-party services with a single click, while support teams benefit from improved visibility through connection logs and alert monitors. The company plans to phase out traditional credentials in favor of connections due to their enhanced features and encourages developers to update their components accordingly.
