Which two benefits do named credentials provide?

Named credentials provide a streamlined and secure way to manage authentication details for external services. By configuring named credentials, you eliminate the complexity associated with individual OAuth flows in each Apex callout. This simplification allows developers to focus on the logic of their integrations rather than handling authentication directly, thus integrating more seamlessly with external services.

In addition to streamlining OAuth usage, named credentials also enhance security. They allow for the secure storage of sensitive information, such as usernames, passwords, and OAuth tokens. By centralizing the management of these credentials in a secure manner, organizations can enforce security policies more effectively and reduce the risk of exposing sensitive data in their codebase.

Together, these features not only help in simplifying the integration process but also play a critical role in maintaining robust security practices within Salesforce applications.
