Unable to log in to Microsoft account in order to renew Realms subscription

Since my account migrated to Microsoft, I am able to log in only by using a reset code sent to a backup email account.

I can log in to Minecraft (koan911), but I cannot change the password, nor renew my Relams account (Dudes World).

I don't feel that my Mojang account migration has truly been successful.  Please help.
