OAuth

OAuth (Open Authorization) is an open standard for access delegation, allowing third-party services to access a user’s resources without exposing their credentials.

OAuth (Open Authorization) is a widely used protocol that enables third-party applications to access a user’s data without requiring them to share their login credentials. For example, if you’ve ever used your Google or Facebook account to log into a different app, you’ve used OAuth. The process works by allowing the third-party app to request specific permissions from the user’s account (like accessing their contacts or profile information). The user grants these permissions, and OAuth generates a unique token that the third-party app can use to access the data.

One of the key advantages of OAuth is its security. Since the third-party app never sees the user’s password, there’s less risk of the password being stolen or misused. The user can also revoke the app’s access at any time without needing to change their login credentials.

OAuth is commonly used for enabling single sign-on (SSO), allowing users to sign in to multiple services with a single account, and it’s widely supported by platforms like Google, Facebook, Twitter, and GitHub.

In summary, OAuth is a secure protocol that allows third-party apps to access user data without exposing login credentials, providing both convenience and enhanced security.
