Enable trading post two factor authentication

[Alastres]

So when I go to the trading post in the dojo i get the message that trading is not allowed with two-factor authentication and I have to "enable it"? I have to enable what, trading?

When I log in to the website (via the game) it just shows my account page and with no further explanation of what I am supposed to enable and where to find it.

Go to Warframe.com, login, go to Account Management and you should see "Enable Two-Factor Authentication" in the lower part of the page.

This was setup so it would be harder for someone to enter your account and steal all your platinum.
