Biggest problem to me is if you are a login with facebook user (or were ages ago), which is highly likely since many websites pushed it hard at the time, some like spotify requiring it. If you log back into spotify while its still deleting, even to move your account to a regular spotify account, it permanently reactivates your facebook account. You have to do all the cleanup, app deletion, etc beforehand.
If you delete your facebook account and had your spotify account associated with facebook, now you cannot login into spotify anymore with your email account. It happened to me, it's a very stupid thing, and as it seems, they (spotify) can't or wont do anyting about it..
I use Spotify and never connected it to Facebook. It's not actually required. They just make the "social" features of Spotify super hard to use if you don't connect to Facebook, which... doesn't matter.
You an migrate Spotify out of the login-with-Facebook thing. Make a new account (or I think they can do that for you too) and then ask them to migrate your stuff to the new account. They migrate most things including your followers but not followees [word?].
I believe what they meant is that you have to "Login with Facebook"and migrating your account before deactivating Facebook, not that they didn't know how to migrate Spotify.
I deactivated my Facebook before, and I had to go through each individual app and either migrate the account to a native login or completely revoke access from the app, if I didn't want them to undo the deactivation when I logged in later, Spotify included.
I feel like they should put some sort of separation between the "Login with Facebook" feature and the Facebook app itself, so that logging in personally reactivates the account but logging in via an app simply verifies the credentials.
No, they allow migrating, but doing so will cause facebook to reactivate your account. Basically, using any 'login with facebook' service after deactivating your facebook account will reactivate you.
I’ve noticed that any online game these days (Fortnite, PUBG, as examples) either want you to link your Facebook account. With some that seems to be the only way to not have a guest account.
