Resetting the RDS master user's password is simple enough, but how do you find your master users username?


The master user name can be recovered with the rds-describe-db-instances command.

If you are using aws cli-2, command shall become :

aws rds describe-db-instances --region ap-south-1

    The 2nd link is no longer working – Raptor Oct 25 '17 at 3:45
  • Good news, the second link works now. But the first doesn't. – simpleuser Feb 18 '19 at 21:26
  • the attribute from that JSON object is MasterUsername – Andre Leon Rangel Feb 23 at 20:16

The master username is now listed in the RDS Dashboard.

  1. Select the "Instances" listing and expand the DB instance.
  2. Press the looking glass tab on the left.
  3. The master username is listed in the left column.

Hope this helps!

    Nice answer as it doesn't require the API. I might add that label/field name in the GUI is not 'Master User' but simply 'Username', which (as of this writing) currently appears under the 'DB Name'. – Andrew S Mar 29 '16 at 21:34

    In 2020, the master user name is now under RDS > Databases > Choose Desired Cluster or Database > Configuration > Master username – MillerMedia Jul 26 '20 at 4:50

It is 2019 now. It is 'Databases' on the sidebar, 'Configuration' on the navigation bar. And look for username.


Navigation bar

  • where can I get the password for the user? – Sazzad Hissain Khan Mar 23 '20 at 5:54

With the new updated RDS UI, the username is present in the Details section of the Instance Information screen.

  1. From the List of your running Instances, click an instance name to see information about the instance.
  2. See the "Details" section of the information screen.

rds instance info screen

scroll down in that screen to see the "Details" section.

your connection information is shown here

  • In amazon aurora, it's under the "Configuration" tab – Savvas Radevic Nov 15 '19 at 8:39
  • I see no instance tab on my aws console – Sazzad Hissain Khan Mar 23 '20 at 5:51
  • For Amazon Aurora, it's in the "Configuration" tab of the cluster entry under "Availability". The label for it is "Master username". – jebeaudet Jun 5 '20 at 17:32

Here is the command that you can use to get the master username of your RDS:

aws --profile=prod rds describe-db-instances
    --region us-east-1
    --db-instance-identifier YOUR-RDS-IDENTIFIER-HERE
    --query 'DBInstances[*].MasterUsername'

Note: Replace the prod with your aws profile and YOUR-RDS-IDENTIFIER-HERE with your rds instance identifier

It will give you the master username like this:


Hope that might help future reader.

  • the above methods using the UI (including looking at the snapshot) did not work for me but this did. I didn't provide the --profile-prod because I wasn't sure what profile I had and it still worked as expected. – almel May 7 '20 at 23:08
  • All of the answers that use the console become out of date so quickly (it's why i'm here today). The API will work for years. Do it this way everybody. – andrew lorien Oct 1 '20 at 4:33

I do not know how to directly find the aws admin username in 2019 AWS, however, you can see it in a snapshot. Just follow:

Main RDS console > Snapshots > A snapshot of your database > Details > Master username

  • Only this method works for me! – khiav reoy Feb 11 '20 at 13:14

Using AWS CLI to get all Instance names + the respective Master users:

aws rds describe-db-instances | grep -e \"DBInstanceId -e Master
SELECT grantee 
FROM  sys.dba_role_privs 
WHERE granted_role='RDS_MASTER_ROLE' 
AND admin_option ='NO';
