The CLI is an open source tool built on the AWS SDK for Python (Boto) to perform setups, determine if calls work as intended, verify status information, and so on. The CLI provides another access tool for all AWS services, including S3. Unlike the Management Console, the CLI can be automated via scripts.
To authenticate your AWS account to the CLI, you must create a configuration file to obtain your public key and secret key. Next, you will install, and then configure, the AWS CLI.
In this exercise, we will configure the CLI with our respective AWS Access Key ID and AWS Secret Access Key. The following are the steps for completion:
Go to.: https://console.aws.amazon.com/console/home and then, click on Users:

Store the keys in a safe location. Protect your AWS account, and never share, email, or store keys in a non-secure location. An AWS representative will never request your keys, so be vigilant when it comes to potential phishing scams.
Open the Command Prompt and type aws configure:
You will be prompted for four input variables, one by one type your respective information, then press Enter after each input:
