I'm guessing the site does not make that available for things like that and may not be using that at all.
OAuth2 for websites ( Sign in with Chess.com )

I need this for my discord bot for quick authentication, I hope someone has an answer for this issue. If Chess.com has OAuth2, it completely lacks documentation for it.
sorry I can't

I want them to enable this. I went directly to Chess.com support and got referred here. Whether or not it's a bad decision by support to automatically ignore the clear feature request I am unsure, but here I am.

Chess.com allows logging in with a Google account, Apple ID (both of which use OAuth) or Facebook (not sure what Facebook uses).

I cannot prove you own Magnus Carlsens account in any way without Chess.com using OAuth2 itself

Add me, try using that logic against my bot.

I'm not trying to use anything against your bot. I'm pretty sure the Chess.com developers haven't implemented their own OAuth service (or any other similar authorisation service). If they did, I'd be kind of worried about the security of their implementation because the site isn't known for flawless code.
I'm sure a people would appreciate it, though, considering how many chess streams are there on Twitch and Youtube.

I have already confirmed they have it, but it's not public.

Have you reached out to the chess.com developers? For example, you could PM the SA of this club. I'm only aware of the API that has been published.

I reached the only person who didn't immediately redirect me - founder of Chess.com - erik. I reached him because 3 years ago he replied to someone regarding OAuth2.

I guess you can use existing API to get user profile, then check if specific adnotation exists in his description. For example thatUser@discord.bot I think there are aready few services doing that.

That's already used, but it's bad.
They intend to let me use their OAuth system, but I still asked them to make it public.
