AWS Multi-session Support
Dave @ 2025-12-02
A major issue with working in an AWS environment beyond a trivial size has always been that you can only use the Console on a single account at a time. This had lead to all sorts of workarounds such as using incognito windows or additional browser profiles.
AWS fixed this (mostly) in January this year by adding multi-session support.
What is it?
Multi-session support is pretty much what it says on the tin. You can now be logged into multiple AWS Console sessions at a time.
This is handled by using a custom domain name for each of your AWS Console sessions, to maintain a separate session cookie for each.
How do I get it?
You need to enable multi-session support before you can use it. This can be done by selecting "Turn on multi-session support" in the AWS Management Console or by selecting "Enable multi-session" on https://console.aws.amazon.com.
Caveats
There are a few things to keep in mind when using multi-session support.
- You can only be signed into up to five sessions at a time. If you attempt to sign in to a sixth session, you'll be prompted to sign out of one of the existing ones.
- When using SSO, signing into the same role twice will count as two different sessions (this may depend on your organization's setup).
- Not every single part of the Console supports multiple sessions properly. The coverage of this has gotten much better since launch, but there are still a few odd corners that don't.
