Comprehensive and Detailed Explanation From Exact Extract:

Named Credentials in Salesforce are used to securely store external service endpoints and

authentication details such as client ID and client secret. When integrating with Google Ad Manager,

the client and secret are used for OAuth authentication. Named Credentials simplify authentication

handling for callouts by managing tokens automatically and securely. Connected Apps are typically

for OAuth client registration but not storing credentials in this use case.
