Both bucket policies and access control lists ACLs are resource-based policies.

Each bucket and object have an ACL associated with it. An ACL is a list of grants identifying grantee and permission granted. For your bucket, you can add a bucket policy to grant other AWS accounts or IAM users permissions for the bucket and the objects in it.

Access policies you attach to your users in your account are called user policies. A document that defines who can access a particular bucket or object. The document defines what each type of user can do, such as write and read permissions.

Or is it simply not typically used in a scenario where the files should not be public? Is there another service for something like this? You can implement Query String Authentication , which will solve your problem.

Query string authentication is useful for giving HTTP or browser access to resources that would normally require authentication. The signature in the query string secures the request.

Amazon S3 resources are built to be private. This means, only the resource manager or administrator, can gain access to the resource. The resource owner can deliberately give access permissions to others by assigning a different access policy. Amazon S3 proposes access policy alternatives largely classified as resource policies and user policies. Access policies are those users add to their resources such as buckets and objects and referred to as resource policies.

Organizations can also add access policies to users in their account. These are generally called user policies. Corporations have the possibility to opt to use resource policies, user policies, or a mixture of these to administer permissions to their Amazon S3 resources.
