OAuth2: The Delegation Protocol

Hello! Today, we're diving into OAuth2, a crucial protocol for securing modern web and mobile applications. It's all about granting controlled access.

Think about how many apps connect to your social media, cloud storage, or email. OAuth2 makes these connections secure without you handing over your main password.

In the past, if a third-party app (like a photo editor) needed to access your photos on a service (like Google Photos), you'd often have to give that app your Google password.

This was a huge security risk! The app would then have full access to your account, not just your photos, and could store your password unsafely.
