AWS: Create IAM User

Create IAM user AWS with [ Access type: Programmatic access ], I named mine ex3_s333

1. Next step "Set permissions" -> Click "Attach existing policies directly"
2. Then search with keyword "s3"
3. To make things simple I chose/checked option "AmazonS3FullAccess" policy name
4. Click "Next:Tags", I am not setting tags here.
5. Finish the process, click "Next:Review" -> click -> "Create user"
6. For ease of use, REMEMBER to download the CSV (contains this new user's access info) -> Save file -> Keep it safe ;)
