AWS Sign-In

Concept

AWS Sign-In is the door into an AWS account, where your identity is verified before you enter the AWS Management Console. The sign-in path depends on who is signing in. The root user signs in with the email address used to create the account, and an IAM user signs in with the account ID or alias and their own user name. With IAM Identity Center, employees can use single sign-on from one access portal to reach several accounts. After signing in, what each person can do is decided by IAM permissions.

Simple example

The entrance gate of an office building, where you show your ID card to get in.

Why it’s needed

So the wrong people can’t get into the account. There is also a record of who signed in, and when.

Where it’s used

Signing in to AWS as the root user, as an IAM user, or through the company’s single sign-on.

Azure equivalent

Microsoft Entra ID sign-in

Remember

Sign-In = the entrance to AWS. Adding MFA (a second check) on top of the password makes the door much stronger.
