You are looking to print photos that you have saved on a cloud storage account using a third-party online printing service. After successfully logging into the cloud account, you are automatically given access to the third-party online printing service. What allowed this automatic authentication to occur?

Answers Explanation & Hints:

The cloud storage service is an approved application for the online printing service, which allowed for the automatic authentication to occur. When two online services have a pre-existing partnership and authorization, they can allow automatic authentication for the user. This means that once the user logs into one service, they can automatically be logged into the second service without the need to enter their credentials again. In this case, since the cloud storage service is an approved application for the online printing service, it has the necessary permissions to authenticate the user and grant access to the online printing service.

The other options listed are not likely scenarios that allowed for the automatic authentication to occur. If your account information for the cloud storage service was intercepted by a malicious application, the attacker would not be able to authenticate with the online printing service. If you were using an unencrypted network, your password could potentially be intercepted, but this would not allow for automatic authentication. If you entered the same password for both services, this could allow for authentication, but it would not be automatic authentication.
