Poloniex two-factor authentication red circle??

[sarannah]

I have Poloniex account Level 1.

Now in Poloniex top right in tools? menu is red circle and if i click it, Two-factor authentication has red circle in dropdown menu.

I don't dare to click there if Poloniex forces me to go Level 2 or some other crap.

Anybody know what this is about?

Poloniex help pages don't tell what this is about.
