The next sections are **not necessarily "advanced"**.

And it's possible that for your use case, the solution is in one of them.

	bucketConditionStr := fmt.Sprintf(`["eq", "$bucket", "%s"]`, bucketName)
	// Add the key condition, only accept keys equal to the one passed.
	keyConditionStr := fmt.Sprintf(`["starts-with", "$key", "%s/upload.txt"]`, objectKey)

	// Combine all conditions into one string.

		// `KeyMarker` is set. It contains part of the objectname as `KeyPrefix`.
		// `MaxUploads` is set equal to the number of meta data entries in the result, the result contains only one entry.

And it can also be used by yourself, to debug, check and test the same application.

## The `password` flow { #the-password-flow }

Now let's go back a bit and understand what is all that.

The `password` "flow" is one of the ways ("flows") defined in OAuth2, to handle security and authentication.

OAuth2 was designed so that the backend or API could be independent of the server that authenticates the user.
