Please work to improve 2 factor authentication with the MS Authenticator app: It stops working for weeks at a time, even with renrollment.
I was faithfully using 2 factor authentication, as encouraged by Yahoo, but it seems to stop working (at least with authenticator apps such as Microsoft Authenticator). Re-enrollment doesn't appear to work and all codes are rejected as "invalid". Please work to improve this, as it's hard to encourage users to use something that works so unreliably.
