How to Get an AWS Access Key

An AWS access key is used to programmatically interact with services from Amazon Web Services (AWS). It consists of two parts:

  • Access Key ID (public identifier)
  • Secret Access Key (private, like a password)

Step 1: Sign in to AWS Console

Go to the AWS Management Console and sign in with your account credentials.

Step 2: Open IAM (Identity and Access Management)

Navigate to IAM, which controls users and permissions.

  • In the search bar, type “IAM”
  • Click on the IAM service

Step 3: Create or Select a User

  • Go to Users
  • Either create a new user or select an existing one
  • Ensure the user has appropriate permissions (e.g., via policies or groups)

Step 4: Create Access Keys

  • Inside the user page, go to the Security credentials tab
  • Scroll to Access keys
  • Click Create access key

You may be asked to choose a use case (e.g., CLI, application). Select the one that fits your scenario.

Step 5: Save Your Keys Securely

AWS will show you:

  • Access Key ID
  • Secret Access Key

Important: The secret key is only shown once. Store it securely (e.g., password manager or secure vault).

Example AWS Access Key (Fake)

Here’s what an AWS access key pair looks like:

Access Key ID: AKIAIOSFODNN7EXAMPLE  
Secret Access Key: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY

Never share your real keys publicly or commit them to source code repositories.

Best Practices

  • Use IAM roles when possible instead of long-term keys
  • Rotate keys regularly
  • Limit permissions using least-privilege principles
  • Enable MFA (multi-factor authentication)
  • Store secrets in tools like AWS Secrets Manager or environment variables

AWS Access Keys vs Other Providers

While AWS uses access keys for API authentication, other platforms follow similar patterns. For example, a cloudflare access key serves a comparable purpose for authenticating API requests within Cloudflare’s ecosystem, though naming and management details differ.

Common Mistakes to Avoid

  • Hardcoding keys in code
  • Sharing keys in screenshots or emails
  • Using root account keys instead of IAM users
  • Forgetting to deactivate unused keys
