AWS console sign-in events - AWS CloudTrail

AWS console sign-in events

CloudTrail logs attempts to sign into the AWS Management Console, the AWS Discussion Forums, and the AWS Support Center. All IAM user and root user sign-in events, as well as all federated user sign-in events, generate records in CloudTrail log files.

Example records for IAM users

The following examples show event records for several IAM user sign-in scenarios.

IAM user, successful sign-in

The following record shows that an IAM user named Anaya successfully signed into the AWS Management Console without using multi-factor authentication.
