If I don't own my Xbox one and have a Xbox series X, can I still sign in to my old account?

Hello Noel how are you?
My name is Ezequiel I'm an Independent Consultant. Yes, you can log into your account on any console, from Xbox 360 to Xbox Series X. You can recover your account even if you no longer have the verification code, please fill out this form with as much information as possible.

Hi George! My name is Stephanie and I'm more than happy to help you out!

Here's what you can do in order to share your Xbox Game Pass on both Xbox Series X and old Xbox One console.

Sign in to your account where you have an active Xbox Game Pass on Xbox Series X console > press the Xbox menu button > go to Settings > Personalization > My home Xbox > Select Make this as my home Xbox.

That way, you will be enabling the game and subscription sharing from your account and all of the accounts that will be using the Xbox Series X console will have the benefits of your Xbox Game Pass subscription.

Sign out of the console then sign in on your old Xbox One console. In this way, you will be using the old Xbox Console where you can frequently use your account. As long as your account is signed in on your old Xbox One console, you will still have access to your Xbox Game Pass benefits while your kids can play your game pass on Xbox Series X console.

Kind regards,
Stephanie

I don't want the same account to be signed in on the Xbox One and the Series X, cause then none of us can play.

Blue Duck has 1 month of Ultimate, and we don't own FH5 and MSFS

I'm doing a flight with my main account (OrangeDuck) but I have to have blueduck signed in to, but if my brother wants to play on the other console, since we don't have the disc, he has to use the gamepass blueduck account and if were signed in at the same time you cant play anything.

I have the digital game and I bought it on the same account that I am signing into the new Xbox and when I download the game it still says I don’t have the game and I can’t play any of the games that I bought in my old Xbox on my series x.

I have not, but as I mentioned Personalisation was working on the Xbox One with no issues. It is on the Series X where this issue has occurred so I don't think it is to do with my account.

I have even done a console reset which removes my account, but still the same. Something is happening between Xbox Live and my Series X or it is the console itself and not Xbox Live.
