You can use your Microsoft account to log in to Classcraft. If you didn’t sign up using your Microsoft account, you can link your Classcraft and Microsoft accounts from your game profile by clicking on the “Link Microsoft Account” button:
Log in with your Microsoft account from the pop-up screen to link your accounts. If you wish to unlink your accounts after they’ve been linked, click on “Unlink Microsoft Account.”
When your Classcraft and Microsoft accounts are linked, you can upload files directly from Microsoft OneDrive wherever you can attach files (such as when creating a message, a Boss Battle question, a quest or an objective, etc.).
To upload files from your Microsoft OneDrive, hover your cursor over the paperclip icon and click on the Microsoft OneDrive icon () when it’s displayed. If your account is not linked, you’ll be prompted to log in.
