+**Note:** The Next.js adapter currently doesn't support customization of cookie attributes from the server side, and cookies are always set with [default attribute values](https://github.com/aws-amplify/amplify-js/blob/2447917fb47ff616aca6f5d64f9c635cf738c7e3/packages/aws-amplify/src/adapter-core/storageFactories/createKeyValueStorageFromCookieStorageAdapter.ts#L10-L15).

+If you are changing the cookie store on the client side, you may need to manually set the cookie attributes to match the server-side configuration. If you need to customize the cookie attributes, you can use the lower level [`runWithAmplifyServerContext` function](/gen1/[platform]/build-a-backend/server-side-rendering/) instead.
