Microsoft account keeps asking 2 factor authentification

Hi

My school Microsoft account keeps asking 2 factor authentification when I try to acces account after closing my browser (on all websites: Teams, Outlook, OneDrive).

I am aware that there are already a lot of questions on this forum regarding this problem, but these always get fixed by disabling the 3rd party cookies or the shields for the these websites. However, if I do this, it still won’t store my account information after closing the browser.

My account does get rememberd by other browsers on my device.

@KobeT,
If you disable Shields for these sites, then it should be saving all your data normally without anything getting blocked. What is the exact behavior if you disable Shields for the relevant MS sites and try to login?
