Greetings Tenno!
As many of you know, Warframe uses a Two-Factor Authentication system (2FA) to help provide account security for our PC Tenno. In an effort to help people better find help documents and report issues, we are giving this system a name:
TennoGuard 2FA!
The base benefits (such as the Fae Path Ephemera) and process are the same as the previous, unnamed system - the details of which can be found on this support page: https://digitalextremes.zendesk.com/hc/en-us/articles/360028551411-Warframe-Two-Factor-Authentication-FAQ
If you have any issues with TennoGuard 2FA, you will find a convenient button on our support pages to help you navigate to the appropriate area. Remember, TennoGuard 2FA is required for PC players wishing to use the in-game trading system, so sign up and protect your account, Tenno!
