In my case the email confirmation popped up every time I created a new account or reset things but sometimes it’s optional if you log in from the same device. I skipped worrying about it after the first one and just made sure to click through when prompted.

It lined up with how my sessions went smoothly afterward.

Some players set up two-factor options later to make future logins even easier without extra emails.
