I was at my computer, and I noticed that Spotify started to play music. I thought that was weird and paused it, only for it to resume 5 seconds later. I quickly logged on to my Spotify account and clicked “Sign Out Everywhere.”
I changed my password and thought that would be the end of it. Logged back into the desktop Spotify client and started listening to music. After 5 minutes, the music stopped, and I noticed it had started playing something else. I contacted Spotify support ASAP to find out how this person was getting access to my account, and they pointed out that my Spotify account was linked to a PlayStation account.
So I fired up my Ps4, went to my account page and noticed that I had suddenly gotten (without me ever playing the game) very into Fortnite and had gotten a couple of new friends added to my friends' list.
I changed my PlayStation password and got help with activating 2FA and had them log my account out of all devices.
Luckily they didn't get access to my payment options as I make it a rule not to remember card details or the PayPal login. But I could have found myself in debt due to some person really wanting some Fortnite V-Bucks.
