Office 365 sign in loops back to the login screen every time

I enter my email and password for Office 365, approve the code on my phone, and it drops me straight back to the sign-in page. Tried Edge and Chrome. Is this something on Microsoft's side or my browser?

Sign out of every account inside Office first - File, Account, Sign out - and close all the Office apps. Then open Credential Manager from the start menu, go to Windows Credentials and remove anything with MicrosoftOffice or your work address in the name. That cached token is usually what keeps throwing you back to the login screen. Also check Settings, Accounts, Access work or school. An old employer or school account sitting in there will fight with the one you're actually trying to use. Restart, then sign in once.
