Hey @Kimwwww

I suggest you contact support so they can help you transfer all your stuff to a non-Facebook Spotify account that uses a username and password to login. You will need to create a new Spotify account that uses a username, and include that username with the description of your problem when you are contacting support.

If you get an automated reply email telling you to check the help section or the community, you need to reply back to it, even if it's from a no-reply address.
Support usually replies within 24-48 hours.
Hey there you, Yeah, you! 😁 Welcome - we're glad you joined the Spotify Community! While you here, let's have a fun game…
