My profile picture and username is no longer my facebook name or picture

My username is now a bunch of numbers instead of my name and I no longer have a profile picture

Hey there! Happy to help. 

Your username is designed to identify you on Spotify, so you can't change it. You don’t need your username to log in. Instead, use your email address and password or log in with the method you used to sign up e.g. Facebook, Apple, or your phone number.

There is more information about this here. 

Have a great day!
