The short answer is once per day. Your OTP (6-digit code) is part of the login process to NCEdCloud, so if you typically login to NCEdCloud more than once during the day (you use different computers, tablets, etc. or logoff and close your browser during the day), you will need to enter your OTP on the 3rd screen of the login. If you use the same machine throughout the day, then you’ll only login (and enter your OTP) once.
