Then we can use `secrets.compare_digest()` to ensure that `credentials.username` is `"stanleyjobson"`, and that `credentials.password` is `"swordfish"`.

{* ../../docs_src/security/tutorial007_an_py39.py hl[1,12:24] *}

This would be similar to:

```Python
if not (credentials.username == "stanleyjobson") or not (credentials.password == "swordfish"):
    # Return some error
    ...
```

	if err = json.NewDecoder(resp.Body).Decode(&idpToken); err != nil {
		return nil, err
	}

	return &credentials.ClientGrantsToken{Token: idpToken.AccessToken, Expiry: idpToken.Expiry}, nil
}

func main() {
	flag.Parse()
	if clientID == "" || clientSecret == "" {
		flag.PrintDefaults()
		return
	}

	sts, err := credentials.NewSTSClientGrants(stsEndpoint, getTokenExpiry)
	if err != nil {
		log.Fatal(err)
	}

	"github.com/minio/minio-go/v7"

)

func main() {
	s3Client, err := minio.New("minio-server-address:9000", &minio.Options{
		Creds: credentials.NewStaticV4("access-key", "secret-key", ""),
	})
	if err != nil {
		log.Fatalln(err)
	}

	var opts minio.GetObjectOptions

	// Add extract header to request:

	if len(authFields) != 2 {
		return auth.Credentials{}, false, ErrMissingFields
	}

	// Then will be splitting on ":", this will separate `AWSAccessKeyId` and `Signature` string.
	keySignFields := strings.Split(strings.TrimSpace(authFields[1]), ":")
	if len(keySignFields) != 2 {
		return auth.Credentials{}, false, ErrMissingFields
	}

	return checkKeyValid(r, keySignFields[0])
}

   to use a memory-hard function (Argon2) that (on purpose) consumes a lot of memory and CPU.
   The new KMS-based approach can use a key derivation function that is orders of magnitudes
   cheaper w.r.t. memory and CPU.
- Root credentials can now be changed easily. Before, a two-step process was required to
   change the cluster root credentials since they were used to en/decrypt the IAM data.
