Eufy/Anker Community sites sharing login and not prompting 2FA?

Hey @AnkerSupport I see my Eufy Security login also works at community.anker.com … but interestingly comes up with a different screen name and no history of activity here. Also it didn’t prompt for 2FA.

Is that normal behavior? Should there 1) be 2FA and 2) be the same account / screen name as this community forum (accessed via menu in the eufy security app) ?
