What is the best way to write user_id in Cookie?

Question

MySQL

I have a database and it has a user_id line
And it is written in Cookies, that is, it determines whether a person is authorized or not. But I still need a user_id to access the Database through it, and if a person changes the user_id in Cookies, what should I do then?

Answer 1

Either sign the cookie or store the user_id in the session.
Well, use httpOnly for this cookie

Answer 2

Everything related to authorization should use sessions and not cookies.
