Question: Which of the following is an example of how you interact with OAuth on a daily basis?
- You sign into Facebook by tapping a message in your Facebook mobile app.
- You sign into a shopping site with your Google login information.
- You sign into your email by receiving a 6-digit code through text message.
- You scan a QR code from your WhatsApp mobile app to log into WhatsApp on your computer.
Explanation
OAuth 2.0 is used when a user authorizes one application to access protected resources through another trusted service. The user does not share their password with the requesting application. The application receives an access token after the authorization flow is completed. In Amazon Ads workflows, the same model allows approved applications to access advertiser resources through the Amazon Ads API. The key concept is delegated access, not direct credential sharing.
Why the other options are incorrect
Facebook mobile approval This describes app-based login approval, not the typical OAuth delegation pattern.
Text message code This describes multi-factor authentication, not OAuth-based delegated authorization.
WhatsApp QR code This describes device linking, not granting a third-party application authorized access.
