What should a user do if the user loses an IAM secret access key?
Retrieve the secret access key by using the IAM console.
Create a new user with a new access key and a new secret access key.
Rotate the secret access key.
Request a new secret access key from AWS Support.
Explanations:
Secret access keys cannot be retrieved after they are created; they must be regenerated if lost.
Creating a new user is unnecessary; the user can create a new access key for the existing user.
Rotating the access key is the recommended solution, which involves creating a new key and disabling the old one.
AWS Support cannot provide or regenerate secret access keys for security reasons; this is the user’s responsibility.
It appears that the answer is:
Rotate the secret access key.
