Do you lose your username after connecting to Facebook?

[stein_bagger]

I have registered on Sporify with a username instead of signing up with a Facebook account. Now I would like to connect my Facebook account to this user and I do not want to lose my username, i.e. I still want to be able to login with my old username. Is this going to be possible after connection to Facebook?

Yes, you will keep your username if you connect a FB account to an existing Spotify account.

Yes, you will keep your username, but your Facebook profile name will now be visible as your user "full name".
