To connect to a Tair (Redis OSS-compatible) instance, you must use a password for authentication.
You can specify a password when you create a Tair instance. You can also set or change the password of an instance in the Tair console after you create the instance. For more information, see Change or reset the password.
You can enable password-free access for a Tair instance to allow the instance to be connected without using passwords. For more information, see Enable password-free access.
