How can I change the account in minecraft when signing in without it assuming, or how can I...

Hello Jismil, sorry to hear you're having trouble.

First I wanted to mention that as this is an open forum our ability to help is limited only to advice. What I can suggest to you would be to read through this post https://answers.microsoft.com/en-us/outlook_com... on the steps you can take to recover your account.

Hello

You can find steps on how to change your sign in preferences on Xbox One right here

As for the signing in without password I assume your Xbox is on Instant on so it doesn't fully shut down when turning it off yet it goes in a sleep mode. You can change that right here

So whenever I log onto Minecraft with my Microsoft account it logs me into Xbox/Microsoft related apps with that account, that’s just a bug? I hope they resolve it or change it in some way so I can login to a different account on Xbox then a different account on Minecraft without having to keep signing in and stuff. Also how do I reinstall the old Minecraft launcher or find it on my pc, I deleted it after installing the new one

I don’t know the password

Hello again, if you don't know your password, you have to create another one, for that, after entering your email, you will click that you forgot your password.
