# RDS instances should be configured to use a custom administrator name
 
## Description{% #description %}

This check determines if the admin username for an Amazon RDS database instance has been altered from its default setting. It's essential to assign a distinct admin username when setting up an Amazon RDS database as default usernames are widely known, this minimizes the risk of unauthorized access.

note: this check excludes Neptune and DocumentDB Databases

## Remediation{% #remediation %}

To update the admin username for an Amazon RDS database instance, initiate the [creation of a new RDS database instance](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_CreateDBInstance.html) and assign a unique admin username during the setup process.
