How can I transfer my Xbox profile to another email account?

Well we did change it so one of my my emails is an alias. Although when I change something on my Xbox it still changes his hotmail. Not only but it’s frustrating as we use 2fa and he changes the password often. How can I have it so logging in to Xbox using my email has one set password and doesn’t change his email but mine if that makes sense.

Sadly that's not possible
I mean, everytime that you or him change the password the system is going to ask that new password everytime in all the sites/devices where the account is logged in (for security reasons)

There is something called "app passwords" in the advance security tab: https://account.microsoft.com/security

But is intended to be used in old systems. You can try it, but I can't guarantee you nothing

Nope, not at all, a Microsoft advocate is going to tell you the same

All those services, are you say. Are different but they're integrated with your Microsoft account.

Something similar happens with Apple, Google, Amazon.
Just to give you a detailed example:
When you create an AppleID and you get an appstore account, Apple music account, appletv account, iTunes store account, game center ("Xbox") account, etc.

I don’t understand why this would be, Xbox is an entire different service than outlook, Skype, office etc. Microsoft really needs to change this.

Also could people at Microsoft help with this issue at all?

the email is the Microsoft account, the Microsoft account IS the Xbox, skype, office accounts etc etc. one password controls it all. you cannot have separate passwords for the same account

you will need to create your own account and then set your dads account as home on the console so you can access the content.

anything you do to that account will affect your dad, if you get banned then your dad is stuck in a rut big time.
