I just enrolled in university and I need to migrate the school calender to Thunderbird. So I tried immigrating to google calender and it worked flawlessly but when i tried Thunderbird it just isnt working, it needs a password whereas google doesnt, which password would this be? my university password doesnt work but i wouldnt know what else i would use as password. help pls! do i need to configure the calender?

I want to stay on team Mozilla and support them but if i need to use an unknown password i cant possibly be bothered to import it manually.
