OAuth 2.0 Protocol

The video tutorial explains open authentication, which allows users to access third-party applications using credentials from another platform, like social media, without exposing their passwords. It describes how a web application can use social media credentials for login, requiring the application to be registered and approved by the social media platform. The process involves requesting an access token, ensuring the user's credentials remain private and secure. This seamless interaction protects user data from malicious applications.

What is the primary role of open authentication?

• To store user passwords securely

• To create user accounts automatically

• To provide free access to all applications

• To act as a middleman for secure access

In the example provided, which platform does the user use to log in to application XYZ?

What must application XYZ do to allow users to log in using social media credentials?

• Create a new login system

• Store user passwords

• Offer discounts to users

What does XYZ request from ABC to allow user access?

• A password reset

• An access token

• A user profile

How does open authentication ensure the security of user data?

• By encrypting all data

• By requiring two-factor authentication

• By using secret tokens
