In order to disable permission checks and allow development tokens during application development (never in a production build), there are a few steps you need to take, in any order.
1. Ensure your app is in development mode in the dashboard, select App -> Options -> Edit
2. Make sure that a server-side API call has been made to disable auth checks and permission checking
3. Create a user with development tokens
To re-iterate, this should not be enabled on production applications.
