I signed up for fCC with a gmail email, and have never had any problems.
I recently had to delete the email I am subscribed to, and replace it with one from hotmail. Now every time I log in to FCC I have to enter the authentication code that is sent to me by email, and this is very boring. To access the forum, I need to enter a second authentication code, even if I am already logged in to fCC.
If I try to log in with the github or linkedin account (these also added to my fCC profile) the system considers me a new user and I lose all the progress I have made and the certifications.
Why isn’t there an easier way to manage your FCC account and log in?
