IAM USER

What is an IAM user?
An IAM User is an entity created in AWS that provides a way to interact with AWS resources. We don't need to give the root user account and password to interact with AWS services. So, an IAM user is created for the clients to use and interact with AWS resources without hampering any security.

How to create IAM user ?

(Suppose, you want to create an IAM user for admin access only)

1st - Login through root user.
2nd - Now, go to IAM user.
3rd - Click on "users" on the left column.
4th - Now press add users.
5th - Give username as "admin".

password.

11th - Tick on the check box of "administration access", then

14th - Then download .csv file, then click on close.

How to login into IAM user?

Go to AWS console -> Click on the IAM user -> Enter 12 digit account ID -> Give the username - Admin (whatever username you have set while creating the IAM user) -> Enter the password which you have set.

Then when you log in it will ask to change password.
After changing password, you are done and you can use the account.

So, this is how we can create IAM user for particular user groups.
