Answer: By generating S3 presigned URLs with a 7-day expiration period.
The most secure way to temporarily share S3-stored documents with external users for a limited duration is by using S3 presigned URLs. Presigned URLs grant time-limited access to specific objects in the S3 bucket without altering the bucket's underlying permissions. This method allows setting an expiration time for the URL, ensuring that access is automatically revoked after the specified period, which in this case is 7 days.
