Is that DRM bro lol
If you have an offline game, yes. That is precisly what it is.
If you have an online game, that is, online services, then, no, not really. It is just a side effect of the means of loggin in. What you need to do anyways to play the game with something like a persistent user account.
I found COD MW 2020 isn't hackable. It has a strong checker that checks if player really bought their games legally.
That is not, what is happening there. This is an online game. And they even made the offline single player campaign "online". Resulting in lots of frustrated players, because they could not even play the single player portion of the game during release, because their lame servers were not reachable. Proving my point, that it is legit players that suffer from drm.
If you have crucial elements of your game on your server, this goes beyond simply "checking", if the player bought the game. You force it to be an online game. And the game is prone to server failings of any sort, including quitting of the gaming company. If I pay for an offline game, I want to be able to play it, even if the company that made it, ceases to exist.
I think you are worrying about an aspect of game publishing, that is not relevant for the scope and type of games you make. (Unless you try to make an online game, of course). You should be glad, if people would want to pirate your games at your stage of recognition. You have more games published than followers on itch, for crying out loud! You think your authentication process will bring in more players?! The dangers of alienating the players you do have, far outweighs any perceived benefit of having such auth.
And imho it is perceived benefit and not real benefit. (Again, unless you plan on making an online game and merely are struggling with the necessary login stuff. Maybe I misunderstood.)
