 * `availability_zone` - (Required, ForceNew) The available zone ID of an instance to be created, please refer to `tencentcloud_redis_zone_config.list`.
 * `mem_size` - (Required) The memory volume of an available instance(in MB), please refer to `tencentcloud_redis_zone_config.list[zone].mem_sizes`. When redis is standard type, it represents total memory size of the instance; when Redis is cluster type, it represents memory size of per sharding.
-* `password` - (Required) Password for a Redis user, which should be 8 to 16 characters.
 * `charge_type` - (Optional, ForceNew) The charge type of instance. Valid values: `PREPAID` and `POSTPAID`. Default value is `POSTPAID`. Note: TencentCloud International only supports `POSTPAID`. Caution that update operation on this field will delete old instances and create new with new charge type.
 * `force_delete` - (Optional) Indicate whether to delete Redis instance directly or not. Default is false. If set true, the instance will be deleted instead of staying recycle bin. Note: only works for `PREPAID` instance.
 * `name` - (Optional) Instance name.
+* `no_auth` - (Optional, ForceNew) Indicates whether the redis instance support no-auth access. NOTE: Only available in private cloud environment.
+* `password` - (Optional) Password for a Redis user, which should be 8 to 16 characters. NOTE: Only `no_auth=true` specified can make password empty.
 * `port` - (Optional, ForceNew) The port used to access a redis instance. The default value is 6379. And this value can't be changed after creation, or the Redis instance will be recreated.
 * `prepaid_period` - (Optional) The tenancy (time unit is month) of the prepaid instance, NOTE: it only works when charge_type is set to `PREPAID`. Valid values are `1`, `2`, `3`, `4`, `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `24`, `36`.
 * `project_id` - (Optional) Specifies which project the instance should belong to.
