How to keep user stay logged after reload a page. It's not a simple as I thought.

1. User is registered by email and password, then logged in.
2. User is reloading a page.
3. I have a JWT configuration to store token on my local storage.
4. When token is verified, I am authenticating him by JWT authentication, returning THIS user.
5. After this, on appUsers on mongo, I see cloned user authenticated again by JWT... what....

How to keep this user logged using only email and password authentication, I don't want to put a password parameter to JWT, then decode a token, then auth a user by encoded email and password. And I don't want a cloned user, of course.

Thanks for any answer.
