Microsoft 365 – Outlook issue

I am currently using Window 10 with a subscription to Microsoft 365. Outlook is version 2209 (build 15629.20208). I keep getting a message asking for my password. I have changed password with email provider and Outlook, which worked for a day, then the message popped up. I found out the basic authentication has been disabled but is there a work around or solution for this issue. My email provider (xfinity) uses IMAP.
