AWS Access Keys, CLI and SDK

To acces AWS, you have three options :

• 1. AWS Management Console (protected by password + MFA)
• 2. AWS Command Line Interface (CLI) : protected by access keys.
• 3. AWS Software Developer Kit (SDK) - for code: promoted by access keys.

Access keys are generated through the AWS Consle

Users manage their own access keys

Access Keys are secretm just like a password. Dont share them.

Access Key ID ~= username.

Secret Access Key ~= password.
