Hello AdiOdi, welcome to the Microsoft community, I'll be happy to help you today;
I understand that you are unable to reset your Microsoft account password;
Initially I recommend that you try to access the link:https://account.live.com/ResetPassword.aspx
Re-enter the username for the account you are trying to reset and select Next;
Verify your identity and select a verification option for the code to be sent (email or phone);
Click Next;
The code will be sent, enter the verification code and reset the password;
More information on the link below:

Hope it works, see you soon!
