FAQ
Frequently Asked Questions
What is an S3 bucket policy?
An S3 bucket policy is an IAM resource-based policy written in JSON that defines access permissions for the bucket and the objects stored inside it.
Should I verify generated policies?
Yes. All generated policies are template structures. You must review security details, resource identifiers, and access scopes in a staging environment before applying them to production resources.
Does this tool upload my bucket configurations?
No. Policy generation is computed locally in your web browser using JavaScript. No AWS configurations are sent to external servers.
