Yes, me too. Does this mean LinkedIn signed me up again? I want to beleive it's a bug but I don't want to click any links in there.

Update: The username is also obviously auto-generated from my name and not something I would have ever used.

This is what I think is happening.

Pressing "Sign in with LinkedIn" is deceitfully vague, and will create a new account if you don't have one already. So I actually created an account and then immediately deleted it afterwards, but their welcome email was delayed for whatever reason.

Just to be sure, I pressed the "Sign in with LinkedIn" button again and it made me an account again. I waited for the welcome email to come in, and then deleted it once more. I hope that's enough.

If you don't have an account, you shall get a popup from LinkedIn warning you that you're about to sign up and share data with a third party service (a standard oauth form you also see with Google/Facebook/GitHub auth).

If you get the popup, by all means, do NOT confirm or it will create an account. Haven't heard of people getting the popup though, strong hint that all users were magically autocreated.

Yes I didn't get a popup either time so I'm assuming that LinkedIn, in their infinite benevolence, automatically created an account for me.

I did get a popup, but it was automatically closed before I could interact with it.

Isn't this how all of the "Sign in with X" work? It's the same with facebook and google also where you go through the same OAuth flow where it asks if you want to give this third party access to your data.

[sseneca]

My experience is that when I sign up to a service with a previous account, the previous account tells me what data the new service will have access to, and then the new service has a couple of more steps to fully create a new account.

In this example it was "Log in with LinkedIn" -> immediately to the front page. I've never had that before.

Ah, this makes sense. Thanks!
