if someone I share my games with someone who is connected to my xbox account sign in list,...

If you dont have a pass code set up on your account he will be able to access your account. You can set one up by pressing your xbox guide button, system, settings and going to account. I highly recommend it for multiple reason

You should never give your login information to anyone. If you do they can do anything to your account that they want to.

Check the following link to set up a passkey for your account.

Hope this helps bud.

You can also change your password on your account and not give him your new password and if he tried to sign in with your account on his xbox it would ask for the new password and as long as he does not know it he wont have access to your account but would
still have access to your games as long as his console is set as your home console

HI Jaredm9.

You can share your games without give to them access to your account, you need just sign in in your account on the Xbox and your Xbox Live Gold, Xbox Game Pass, and Games could be sharable.
