Hi.  
In your opinion, from a security point of view, is it necessary to add an .env file to a project that receives data from a prismic / slice machine?  
If so, what information should be added to it?  
Do I need to add the name of the prismic repository to the .env file?

Hi @irbris,

Thanks for reaching out.

Well, it depends on your application and repository authentication, so your repository is private, and your application is statically generated. You can probably have a .env file to store private data, such as your access token.
