My school recently introduced Duo 2FA when logging on to our online classroom platform and despite clicking the "Remember me for 30 days" box, Firefox will not remember my computer which means I have to get on my phone to accept a push notification every time I want to log in to the portal. Despite trying various things my school's IT desk has been no help, so I came here because it must be some issue with the Firefox browser itself as it remembers me fine in browsers like Chrome. In my Privacy & Security tab, I am using custom settings and do not have the box checked to block any cookies. In Manage Permissions for cookies I also have always explicitly allowed cookies from my school's portal and duosecurity.com. I also never use private browsing when trying to use this function and don't have Firefox set to clear any of my data when I close it, but I don't need to close the window or anything -- when I try to log back in on the same tab a few hours later, I'm still prompted for a push notification. I've gone as far to reinstall the browser completely, but this hasn't worked either? Does anyone else have this problem or have any other tips? Getting push notifications every 2 hours is really getting on my nerves, especially since all of my classes are online now due to the virus. Thanks!
