Yesterday while i had the spotify desktop app open but not playing music, i noticed someone was listening to music from another device in my account. I then logged out of all the devices but this kept happening and music i've never listened to appeared as "recently played". I then changed my password twice, but again, it kept happening.
Another thing i noticed was that when i logged out from my device and then tried to log in again by clicking the "log in with facebook" button i logged in without Spotify asking me for any type of information. My facebook account wasn't open from my computer, so i don't understand why Spotify never asked for any password or email to be given and just accessed to my account. I then also checked the app Last.fm to see which were the last songs i listened to, and many songs that i wasn't listening to appeared as recently played.
I'm scared someone hacked into my account, so please if there's any way you can help me i'd be more than thankful. I already tried everything. Thank you!
