Hmmm that's odd, just tried both but getting the following error.

Hmmm that's odd, just tried both but getting the following error.

is it a valid Minecraft/Microsoft account?
If it is a cracked launcher or account, I do not support that because the authentication itself is used to generate the wallet and access strings and I don't want to risk spoofing.
Ok so that's why, sounds like its time to get an official account after 10 years haha
