Selected Answer: A
Its A: OAuth authentication provides a secure method for authentication and authorization without exposing user credentials (username-password) to the API service. Instead, OAuth relies on access tokens issued by an authorization server after verifying the user’s credentials. These tokens are then used for API access, ensuring security while preventing direct transmission of username-password combinations.

Selected Answer: B
RFC 7616. This method enhances security by avoiding the transmission of passwords in clear text. It employs a challenge-response mechanism that uses a cryptographic hash function, ensuring that passwords are never sent directly over the network.

While Digest Authentication hashes credentials before transmission, it still involves sending credentials in some form, which contradicts the requirement of not sending them to the API service.
