We added multi-factor authentication to access things like account settings. If you want to access your account settings you’ll need to click on a link in your email to be able to get access to that page. Important: This requires that you have a valid email address in your user profile.
After you click on the link to confirm your identity, you will be taken to your account profile page.
This authentication covers the security for many of the pages under the account menu, and when you click the link in the email it means you won't have to reauthorize for another 24 hours.
