The first time you log in, you'll have to register your account. It should be pretty straightforward.
Head over to portal.liszt.me. You'll see a "Login with Office 365" button. Click it.
The friendly Microsoft login screen comes up that you've probably seen a bunch. Log in.
You'll get a screen that asks if you want to give Liszt Portal access to read your profile. All the info Liszt needs is your name and some identifying numbers from Microsoft.
Here's where it might get messy
If you have a unique name, Liszt will look up your name and attach your Microsoft account to Liszt. You're done! Click the green button and you're logged in.
If your name isn't unique, or you go by a different name, Liszt may have trouble finding you. Liszt will ask for your student ID number. Click the green button and you're logged in.
If Liszt can't find you by your ID number or your name, it'll throw an error that tells you to submit a support ticket.
The next time you log into the portal, you'll click "Log in through Office 365" and after logging in through Microsoft you'll be returned to the portal.
