Do i need to add a alternative sign-in option in my app even though the only option i provide is apple sign-in

i heard that i need to provide an alternative option to create account in my app if i use any third party social platform to create account which is facebook in my case. so i removed the facebook login option and added only apple sign in. now my doubt is, should i provide another option for the player? or is it alright with only apple sign in
