What is OAuth?

OAuth (Open Authorization) is an open standard protocol that enables secure and delegated access to resources on behalf of a user. Rather than sharing sensitive credentials like usernames and passwords, OAuth uses access tokens to grant third-party applications limited permissions to access user data.

How OAuth Works

1. Resource Owner: The user who owns the data.
2. Client: The application requesting access to the user’s data.
3. Authorization Server: The server that authenticates the user and issues access tokens.
4. Resource Server: The server hosting the user’s protected resources.

When a client needs access, it redirects the user to the authorization server. The user then reviews the request and, if they approve, an access token is issued. This token allows the client to access only the permitted data on the resource server.

Key Benefits of OAuth

• Enhanced Security:
  Users never expose their credentials to third-party applications.

• Granular Access Control:
  Tokens can be configured to provide limited access scopes, ensuring that applications access only the necessary data.

• Improved User Experience:
  Users can grant access to various applications without the need to create multiple sets of credentials.

OAuth has become the industry standard for authorization due to its robust security model and flexibility. Llamauth seamlessly integrates OAuth to provide a secure and effortless solution for modern authentication, ensuring secure access to user data while minimizing the risk of compromised credentials.
