Determine which Livejournal account a site visitor is registered under

Question

Open ID

So, there is my site where you can leave comments. The possibility of authorized comments on behalf of the LiveJournal account is required.
There is a visitor who has an account in Livejournal and is logged into it.
There is the same Loginza, which can provide this, but visitors really don’t like it when they need to type in the LJ login and click the mouse once again (especially if they are already logged into LiveJournal).

Ideally, it is necessary that the site itself understand which LJ account came to visit them. Is it possible to do this?

Answer 1

So LJ seems to have OpenID. Do authorization on it and that's it. Well, in a brazen way, no one will give data from LJ. Imagine how easy it would be, a person came to your site, and you know his LiveJournal, Vkontakte, Odnoklassniki, Facebook and other muck .

Answer 2

Gazeta.ru is part of SUP, the owner of LiveJournal, so this feature is exclusive. At least that's how it used to be, things may have changed now.

Answer 3

Only indirectly, through OpenID.
