But how that " process.env.TOKEN\_HEADER\_KEY " stores token in .env file which is generated by jwt.sign()

Hi Mohanish, .env file is used to store sensitive information which can't be made public.

To store data in .env file, the format is TOKEN\_HEADER\_KEY=authtokenheaderkey

and through process.env.TOKEN\_HEADER\_KEY, we can access header key.
