An access key is a unique string of characters used to authenticate and authorize access to a system, service, or resource — commonly used by non-human identities like applications and scripts to access cloud APIs.
⚙️ How Does It Work?
Access keys consist of an Access Key ID and a Secret Access Key. The calling application presents both to the cloud API, which validates them against IAM policies to grant or deny the request.
📍 Where Is It Used?
AWS IAM, Azure, GCP — any cloud platform where applications or scripts need programmatic access to resources.
💡 Real-World Example
A developer hardcodes an AWS access key in a Lambda function to read from S3. The key is accidentally pushed to a public GitHub repo and scraped by a bot within minutes, leading to a cloud breach. Best practice: use IAM roles and short-lived credentials instead.
