I've inherited control of an AWS MySQL RDS instance. I'm curious to know what the 'rdsadmin' user is and whether I should know the password for this or whether this is purely for use by the Amazon Web Console.

1 Answer 1


This is Amazon's own user that is used by Amazon to perform updates, run backups and do other maintenance tasks. That said, Amazon's support should be able to advise you.

In general, you don't need to (and should not) know the password.

    This actually conflicts with what I have been told on the AWS IRC channel. Also, there is the option 'New Master Password:' when modifying an instance. Which user is that for?

    "New Master Password" will reset the password for the named admin user that you created when you spun up the RDS instance, which is a separate account than 'rdsadmin'. What was said on IRC? Apr 9, 2014 at 10:12

    You can check the named admin user's username in the AWS console - it will be in the "Configuration Details" panel of the instance details, and will be titled "User name". The "rdsadmin" user is for Amazon's usage, and the user mentioned here is for your usage. Of course you are free to create other users, but this one is the only one granted with full admin rights.

    @Muhatashim no, because you should never know the rdsadmin user's password. May 19, 2016 at 15:47

    @Muhatashim I cannot stress this enough - you should never need to know, use, change or otherwise interact with the rdsadmin user. May 20, 2016 at 5:34
