You can call this operation to enable or disable password-free access for an ApsaraDB for Redis instance. When the password-free access feature is enabled, Elastic Compute Service (ECS) instances in the same Virtual Private Cloud (VPC) can access the ApsaraDB for Redis instance without the password. You can also use the username and password to access the ApsaraDB for Redis instance.

For more information about how to perform the corresponding operation in the console, see Enable password-free access.
