How to create user IDs in mongodb?

Question

MongoDB

Hello!
I am an eggplant in this area, so I wanted to ask you, maybe the question will sound stupid for many ... But I don’t know how to make it so that when a person registers, he is given an ID. For example, the first person registered and he was given 1ID, and so Further. Thanks in advance.
All good.

The mong already has an id for the entry, the field is _id . Otherwise, how to get records?
