Same here, I don't use it because I find twitter to be a very hostile place. On top of that my old account I registered in 2012 keeps being locked up because I refused to share my phone number - and when I did eventually share it twitter immediately put profiles of my friends as recommended ones, which means that at one point it stole my phone number from my friends' contact list and is now using it without my consent.
I don't use any third party sign in services. Email is the only option. Any third pary (Twitter, Google, Facebook, Github) etc can stop your account, making you lose access to anything you signed in via their account.
