my display name changed suddenly when i didn't change anything

[New user]

about 5 or more times, I caught my display name suddenly changing into a random name such as 317ktziulgyx7vsp6e6prn---- and lost my profile picture. but later it will come back. what's this?

Hey

If you see some random characters, that's your actual Spotify username, which was assigned automatically to you when you created your account through Facebook.

Hope it helps. 🙂
