I'm unable to migrate my Mojang account to a Microsoft account because whenever I login via https://minecraft.net using my mojang details I get asked to input my security questions.

However, It's been a long time since I've had to input any security questions and I can't remember the answers I gave (I try to make them always not so clear for security reasons).

According to the support pages, the only way to reset the security questions requires login in on https://account.mojang.com/login but it seems this is not possible anymore (I keep obtaining an error that my email or passwords are incorrect... which isn't true, I've checked several times and they do get accepted when I use them in https://minecraft.net ..where the questions are asked).
