A lot of students get stuck at the NSFAS login stage, usually because of a wrong password or a locked account after too many failed tries. Your username is always your 13-digit ID number, entered with no spaces, and if you forget the password, you can reset it from the login page using the email or phone number you registered with. Only ever log in at my.nsfas.org.za, since fake sites get shared on WhatsApp groups all the time. I found the full steps and fixes laid out at https://eduaidsa.co.za/ if you want to check them.
