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?
I changed the email to my linkedin account, I didn’t do it to the github account. The problem is that even github always asks for the authentication code sent by email, so using it to access fcc simply means doubling the steps to be recognized. I tried once and will never do it again.
