Easily Switch Between Multiple AWS Accounts


If you use the AWS (GUI) console to manage multiple AWS accounts or IAM Roles, you may have noticed that the Account drop-down menu lists your five most recently used (MRU) IAM Roles and lets you conveniently switch between them. The MRU account menu works really well if you sign into a main identity account and then assume an IAM Role in one or more resource accounts, e.g. dev, test, prod.

However, the AWS account drop-down menu has limitations. Besides being limited to the last five Roles, you cannot filter Roles by account. In other words, if you have five work accounts and two personal AWS accounts and you frequently switch between them, your work and personal Roles will be shown together in the order you last accessed them. As consultants who deal with many different customer accounts we need a better solution, and you may too.
In this post I’ll show you how to use “AWS Extend Switch Roles,”Chrome or Firefox extension which extends the number of IAM Roles beyond five and lets you create groups of related AWS accounts/Roles. For example, when you log on to your Identity account at work, the Account drop-down menu will only show work-related Roles, e.g. dev, test, prod; your personal accounts will not be shown.

AWS Extend Switch Roles Appearance

Here’s what it will look like when we’re done:

Extension Configuration

Once you have “AWS Extend Switch Roles” installed, you need to configure it with your AWS accounts and Roles. Click on the green key icon in your browser toolbar and select Configuration. In the Configuration box you specify a main identity account and one or more resource accounts. For example:

aws_account_id = 123456789012 or <my_identity_acct_alias>
source_profile = identity
role_arn = arn:aws:iam::901234567890:role/app-team-1
region = us-west-2
color = ffcc00
source_profile = identity
aws_account_id = my-staging-acct-alias
role_name = app-team-1
region = us-west-2
color = 0096ff

The extension supports two ways of specifying the IAM role to use for a given account. You can specify the aws_account_id and role_name as in the [staging] profile above, or you can specify an AWS role_arn which should be familiar if you already have an ~/.aws/config file in your home directory for use with the AWS CLI. 

Not Shared with your ~/.aws/config file

The “AWS Extend Switch Roles” configuration sure does look a lot like an ~/.aws/config file, but they are not the same thing. You’ll need to maintain the Switch Roles configuration separately from your AWS CLI configuration.


The extension allows you to specify either the 12-digit AWS Account Number or an AWS account alias which acts as a friendly name for your account. In the configuration example above, the Staging account has an account alias of my-staging-acct-alias. I recommend AWS account aliases since it’s much easier to tell at a glance which account you are in.
Keep in mind that you can’t use the AWS account alias in an ARN, so if you specify the role_arn format above, you’ll need to use your 12-digit AWS account number.

Multiple Groups of AWS Accounts/Roles

The extension really shines when you have multiple groups of accounts. Maybe you have multiple work accounts and multiple personal accounts, or maybe you’re on a Cloud Engineering team and have to work with a lot of different IAM Roles and Accounts.
You can simply specify groups of main identity accounts and related resource accounts in the extension configuration and the extension will automatically filter resource accounts by their source_profile to show you only resource Roles/Accounts which you can switch to from the Identity account. For example, if you have Acme Corp’s Identity account and dev/test/prod IAM roles and Beyond Corp’s Identity account and dev/staging/prod IAM roles in the Switch Roles configuration, then only Acme Corp’s dev/test/prod IAM roles will be available when you are signed in to Acme Corp’s Identity account.


I learned about “AWS Extend Switch Roles” from one of our customers and now I use it every day. I’ve also demoed it to our engineering team where it was received enthusiastically. It’s a big improvement over the standard AWS account drop-down menu for managing lots of AWS accounts. If you are a Chrome or Firefox user, I highly recommend you give it a try.
