+We recommend using the new [Amplify Gen2](https://docs.amplify.aws/gen2/build-a-backend/storage/) experience when defining file access permissions as it offers a more flexible approach to customize access to files.

 When adding the Storage category, you configure the level of access users have to your S3 bucket. You can configure separate rules for authenticated vs. guest users. When using the Storage category to upload files, you can also specify an access level for each individual file: guest, protected, or private.
 
 - **Guest** Accessible by all users of your application
