    void testSubCommand() {

Additionally, we create a `secret_name` for the hero, but so far, we are returning it everywhere, that's not very **secret**... 😅

We'll fix these things by adding a few **extra models**. Here's where SQLModel will shine. ✨

### Create Multiple Models { #create-multiple-models }

다음과 같은 사용자 인터페이스를 볼 수 있습니다:

이전과 같은 방법으로 애플리케이션에 인증하십시오.

다음 인증 정보를 사용하십시오:

Username: `johndoe`
Password: `secret`

/// check

코드 어디에도 평문 패스워드 "`secret`" 이 없다는 점에 유의하십시오. 해시된 버전만 있습니다.

`/users/me/` 를 호출하면 다음과 같은 응답을 얻을 수 있습니다:

```JSON
{
  "username": "johndoe",

		"http://localhost:8080/auth/realms/minio/.well-known/openid-configuration",
		"OpenID discovery document endpoint")
	flag.StringVar(&clientID, "cid", "", "Client ID")
	flag.StringVar(&clientSec, "csec", "", "Client Secret")
	flag.StringVar(&clientScopes, "cscopes", "openid", "Client Scopes")
	flag.IntVar(&port, "port", 8080, "Port")
}

func implicitFlowURL(c oauth2.Config, state string) string {
	var buf bytes.Buffer

  - Navigate to service provider section, expand Inbound Authentication Configurations and expand OAuth/OpenID Connect Configuration.
    - Copy the OAuth Client Key as the value for `<CLIENT_ID>`.
    - Copy the OAuth Client Secret as the value for `<CLIENT_SECRET>`.
  - By default, `<IS_HOST>` is localhost. However, if using a public IP, the respective IP address or domain needs to be specified.

### Authentifizieren
