How to Enable IAM Authentication for AWS RDS PostgreSQL?

We can manage database access for PostgreSQL database instances using AWS IAM thanks to IAM authentication. The steps to enable the process are as follows:

1. Open the AWS RDS dashboard by logging into the AWS Management Console.

2. Select the Postgres RDS instance for which we need to enable IAM.

3. To change the instance settings, click the “Modify” button.

4. To enable “IAM database authentication,” scroll down to the “Additional Config” section and select “Yes” under “Database authentication.”

5. Once the changes have been made, scroll down, select “Continue,” check the work, and then select “Modify DB Instance” to put the changes into effect.

6. Make sure the rights needed to connect with the PostgreSQL DB are allowed by the IAM policies linked to the IAM roles that the apps use.

7. To use IAM authentication, update the connection settings in the app. The app should use an authentication token received from AWS STS using the IAM role linked to the EC2 instance, Lambda function, or other AWS service in place of entering a username and password.

8. After making the changes needed, make sure the app can successfully use its IAM details to use to the PostgreSQL database by testing the IAM authentication.
