1. User will do the login UserName and password.
2. If the login success then server will return JWT.
3. Now we will store the token.
4. Now for every request we will send the JWT Token for authentication on server.
My question is that Where can we store the JWT token because Local storage,Session,Cookies is not safe.
"Only the server should know the "secret" that is used to generate the JWT. If someone modifies the data contained in the JWT, the server will fail to decode it. So the server can trust any JWT that it can decode."
You don't need to store JWT token where someone can't find. And if you think if hackers get token of someone, there is a expiration date option for this.

httpOnly cookie
It's a special kind of cookie that’s only sent in HTTP requests to the server, and it’s never accessible (both for reading or writing) from JavaScript running in the browser.
