Which credential allows programmatic access to AWS resources for use from toe AWS CLI or the AWS API?
User name and password
Access keys
SSH public keys
AWS Key Management Service (AWS KMS) keys
Explanations:
User name and password are primarily used for console access to AWS services and do not allow programmatic access.
Access keys consist of an Access Key ID and a Secret Access Key, which are used for programmatic access via the AWS CLI or API.
SSH public keys are used for secure shell access to instances but do not provide programmatic access to AWS resources.
AWS Key Management Service (KMS) keys are used for encryption and decryption purposes, not for accessing AWS resources programmatically.
It seems to me that the answer is:
Access keys
