Day One account. This is an account you manually set up with an email and a password of your choosing. See here on how to create a Day One account.
Sign in with Apple. This is new as of version 5.0 on iOS and 4.16 on Mac. This option is just the updated version of the previous way of using Apple ID. See here.
- Google Account This will log you in with your Google Account by clicking “continue with Google” in the app
