 ### Algorithm
 
 This part of the algorithm is very important, if you do not know how to learn the algorithm, you can look at what I wrote.

If you are not clear about these concepts, we suggest you read this article properly.
 
 - **JWT** : JWT (JSON Web Token) is a form of authentication, where a JWT is essentially a signed piece of data in JSON format. Since it is signed, the recipient can verify its authenticity. Related reading.

 - **SSO(Single Sign On)**: **SSO(Single Sign On)** that is, single sign on means that a user has the right to access other systems related to him/her by logging into one of the multiple subsystems. For example, after we logged into Jingdong Finance, we also successfully logged into Jingdong Supermarket, Jingdong Home Appliances and other subsystems of Jingdong.
