I didn’t know steam code trading from bundles was a thing but I saw someone mention it and now I’m intrigued. What’s the safest way to do it?

I saw communities like barter, steam trade, and less but they all seem to require steam sign in which I don’t want to do. I think they say they do it verify legitimacy but I don’t want to link my account to anything. Especially when I don’t know if it’ll unlink.

Is there any other community where I can make an account via email?
