Master user account privileges - Amazon Aurora
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China.

Master user account privileges

When you create a new DB cluster, the default master user that you use gets certain privileges for that DB cluster. You can't change the master user name after the DB cluster is created.

Important

We strongly recommend that you do not use the master user directly in your applications. Instead, adhere to the best practice of using a database user created with the minimal privileges required for your application.

Note

If you accidentally delete the permissions for the master user, you can restore them by modifying the DB cluster and setting a new master user password. For more information about modifying a DB cluster, see Modifying an Amazon Aurora DB cluster.

The following table shows the privileges and database roles the master user gets for each of the database engines.
