# What is the difference between UserPool ID, UserPool Secret and OAuth, OIDC App ID and App Secret?

  1. UserPool ID and UserPool Secret are the information of the user pool created by the Authing developer. Through the UserPool ID and UserPool Secret, the Authing developer has all the access permissions of the user pool;
  2. The App ID and App Secret of the OAuth/OIDC application are the information of the OAuth or OIDC application, used to authorize other applications to access the user pool, and can also be used to [verify the legality of the JWT token](../advanced/verify-jwt -token.md).

# What is the difference between the two tokens in the OIDC process?

The OIDC process contains two tokens:

  1. access_token is used to obtain user data;
  2. id_token contains the basic information of the user;

Both can be verified using the secret of the OIDC application. For the verification process, please refer to: Use the key of the OIDC application to verify the validity of the token.

# What standard protocols does Authing support?

The industry standard protocols used by Authing include:

-OAuth 2.0: An authorization standard that allows users to grant limited access to their resources on one site to other sites without obtaining their credentials (usually account passwords). For example, you will use this standard when you click "Log in with WeChat" on your phone, and the system will ask you whether you agree to share your avatar, nickname and other data with the application. -Open ID Connect: This is a superset of OAuth 2.0. It provides more user information and access permissions and standards on top of OAuth 2.0. For example, he defines the user's avatar as picture. -JSON Web Tokens: An open standard, mainly used to transmit information securely. Its format is very compact and independent. After parsing, it is a JSON format. -Security Assertion Markup Language (SAML): An XML-based open data format, SAML allows enterprise applications to seamlessly connect with internal and external programs. -LDAP: LDAP is a lightweight directory access protocol. The full English name is Lightweight Directory Access Protocol, which is generally referred to as LDAP. You can understand it as a tree-shaped database used to store user and organization information, often used for single sign-on (SSO) and corporate employee information management.
