Finally, AWS has a new feature to support multiple AWS accounts in the same browser easily. The problem faced by people using multiple AWS accounts is that you can only log in to one AWS account console at any one time – at least using the same browser. Workarounds include use of different browsers (eg. one console in Chrome, one in Safari etc), use of incognito mode, or – my favourite – use of browser containers in Firefox, but they all come with limitations. Now you don’t have to do that anymore.
Today, AWS announces multi-session support, which enables AWS customers to access multiple AWS accounts simultaneously in the AWS Console. AWS Customers can sign-in to up to 5 sessions in a single browser, and this can be any combination of root, IAM, or federated roles in different accounts or in the same account.
