Right now I'm using 3 different email accounts on Thunderbird. All 3 of them are Office365 accounts. For some reason, 1 of the 3 accounts is prompted at least once a day, sometimes twice a day, to enter my password on the Office365 website popup that is used with the OAuth2 authentication process. It's very irritating, all 3 accounts are Microsoft Office business accounts. What would be the reason why it needs to authenticate daily? Is there no password manager to do this automatically once it's been entered once? Can I pick a different authentication method? What is the correct change to make so I don't have to keep typing in my password every day?
