How can i get information of my all iam users. when they login?

You can use event bridge to monitor cloudtrail APi calls and send a message to an SNS topic. Theres a similar example here but specifically looking at AttachUserPolicy events. Replace this with ConsoleLogin

I believe this should work for you.

AWS makes requests based on API calls.

When accessing programmatically, including CLI, credentials are saved on the local PC and requests are made according to the permissions given to the credentials. Therefore, there is no login during this process.

However, if SSO is linked through Identity Center, SSO Login can be triggered from CLI. By analyzing Identity Center records in CloudTrail, you can see who has access to SSO. For detailed API call names, please check the official documentation [1].

In the management console, users log in with a password. This is not an API call, but it is recorded in CloudTrail. For example, in CloudTrail, if you collect records with an "eventSource" of "signin.amazonaws.com", you can determine which users are logged in. Please check the official documentation [2] for specific records.
