There are three option how to create user login and password:
1. Using QuickBlox SDKs.
This way usually used if you build your application with QuickBlox SDKs.
You can find more information in the Users section in our official documentation for each SDK.

2. Using Server API.
If you do not want to use QuickBlox SDKs, you can refer to our Server API documentation and find more information how to create a user.

It is the manual way to test a user creation functionality and rarely used.
