Minecraft PlayStation 4 Unknown Account Sign In

I have the same issue, though I think I had signed into my Microsoft account earlier. One way or another, I only have one PS4 account, but when I tried logging in I was also told it was connected to a different account. Is there a way to confirm what PS4
account my Microsoft account is linked to?

Hi EmilyySchmiitz

Have you tried signing out of your account/profile and signing back in?

Hey there EmilyySchmiitz,

Thanks for reaching out to the Forums for advice on how to hopefully getting all of your Minecraft information set. I can totally understand how this could be pretty puzzling. The thing is, according to Minecraft, if there is no way to unlink it and link
it to another account. For more information check out this FAQ page they have provided.

Hope this was informative.

Thanks for reading!

Hello Ichigo_Kirigaya,

Thanks for posting on the Xbox forums. We understand that you are attempting to link your Microsoft account to Minecraft for PlayStation 4, but you are getting an error. We recommend
signing in to the Xbox website with your Microsoft account. This will create an Xbox profile for the account. Xbox profile information is necessary on a Microsoft account in order for you to
link it to Minecraft for PlayStation 4. Also, there is
an FAQ on the Minecraft support website that explains more about using Minecraft on PlayStation 4. Be sure to let us know the results
Ichigo_Kirigaya!

You play on PS4 so do you have a Microsoft account? If not get one you need it. Then read through the site I am linking below to see how to do what you want.

Minecraft guide: How to set up Xbox Live for cross-play on Playstation 4

One of the reasons Minecraft: Bedrock Edition took so long to make its way to Playstation is that it requires an active Xbox Live account to enable cross-play features. Xbox Live is powered by a Microsoft Account, and it's completely free for anyone
to sign-up for one, so, fortunately, its not a tall order to fulfill. To connect your Xbox Live account to your Playstation's version of Minecraft, follow these steps:

1. Make sure you own Minecraft on Playstation. If you're not a proud owner of Minecraft on your Playstation yet, you can buy
   it from Amazon or through the PlayStation Store.
   All current PS4 Edition owners will also recieve a completely free update to move to the Bedrock Edition.
2. Make sure you have a Microsoft Account. As mentioned before, an Xbox Live account is powered by a Microsoft Account. These accounts power all kinds of Microsoft services like Outlook, Office 365 and more. If you don't already have one, you
   can create one for free.
3. Make sure you have an extra device. Your Playstation 4 will ask you to access a website from an external device like a phone or computer to sign-in to your Microsoft Account.
4. Open Minecraft on your Playstation 4. You'll sign-in to your Microsoft Account from within Minecraft, rather than your Playstation directly.
   
5. Select "Sign In For Free" when prompted. Upon initial launch into the Bedrock Edition of Minecraft you'll see a message pop up informing you of the advantages of connecting a Microsoft Account to Minecraft.
   
6. 1. Navigate to the displayed website. Minecraft will request that you navigate to https://aka.ms/remoteconnect on your phone or computer.
   2. Enter the code from Minecraft. Looking back at Minecraft, you'll see a code displayed underneath the URL. Enter this code on your device to allow access to your Microsoft Account.
      
   3. Finish the process. A new screen will confirm that your Xbox Live profile is now connected to Minecraft. You can now reap the benefits of Minecraft: Bedrock Edition on your Playstation 4!
