Why I cant login into my minecraft account

I tried to log in to my Minecraft account by Mojang login and failed. So I checked my Yahoo mail and noticed I migrated my Minecraft account to Microsoft login, I completely forgot why I did that! Now I can't log in back to my Minecraft because I don't remember the outlook mail I logged. How can I migrate it back? I tried to get the security key but the system is unable to authenticate. If there is no plan to migrate back to Mojang login, how can I get my refund back? I bought the redemption card from the kiosk back in 2017.

p.s. It's new account I made.

"I tried to log in to my Minecraft account by Mojang login and failed. So I checked my Yahoo mail and noticed I migrated my Minecraft account to Microsoft login, I completely forgot why I did that!":

It started being made a requirement so thats probably why.

"How can I migrate it back?":

You cant as far as im aware.

"If there is no plan to migrate back to Mojang login, how can I get my refund back? I bought the redemption card from the kiosk back in 2017":

Odds are you probably cant and if you could it would probably have to be the kiosk company that would refund you since thats where it was purchased originally.

I cant login onto the mojang site using my microsoft account. It says unknown email or password when im certain its correct. I can login onto minecraft.net and it shows my minecraft profile and my xbox account information. When I try to launch minecraft it say that I need to buy the app again and when I refunded the minecraft launcher it was removed from my device. I had only cancelled a game pass subscription.

Hi i would like to ask why when i try to sign into my ps4 microsoft minecraft account it says there is an error to login
