The user rights confirmation process (authentication and authorization) in Go typically involves the following steps:

1. Authentication — verifying the user's identity, for example, through login and password. In Go, this can be implemented by comparing the entered data with the data stored in the database.

2. Creating a session or token — after successful authentication, a session or JWT token is created, which the client will use for subsequent requests.

3. Authorization — checking whether the user has the rights to perform a specific action or access a resource. This is usually done based on roles or permissions stored in the database.

Example of simplified authentication with JWT:

// Check login and password
if username == "user" && password == "pass" {
    token := generateJWT(username) // JWT generation function
    // Send token to client
}

Then, on each request, the server verifies the validity of the token and the user's permissions.
