Cura is a web based application, so you will need to go your school's Cura web page on-line to log in. Someone in school (typically your network manager) will be able to give you the web page address. You will then see the Cura log in page.
If you are a SIMS user then you can use your SIMS username and SIMS password. Otherwise, your administrator will send a username and password to you.
Cura uses two factor authentication, which means you will need a PIN number as well as a username and password in order to log in. To get your PIN number you will need to download an authenticator, which is an app for your phone or tablet. There are several different authenticators available for free via the Play Story or App Store, any of them will work. You should download before attempting to log in.
Once you have an authenticator, enter your username and password and click the Login button. You will then be shown a QR code - scan this with your authenticator or type the 20 digit number into your phone. Your device will then generate a PIN number for you, which lasts 60 seconds. After 60 seconds, the old PIN number will expire and be replaced by a new PIN.
