Ours is a commercial app for small business, we do provide both the options in the app for the user to login using our company's account setup or using the Google sign-in. So in this case, does Apple mandate to provide the 'apple sign-in' as another option or it is with us to decide?
We went through the guidelines, but the below statements sound contradictory, so we are looking for clarification.
- Apps that exclusively use a third-party or social login service to set up or authenticate the user’s primary account with the app must also offer Sign in with Apple as an equivalent option.
- Sign in with Apple is not required if your app exclusively uses your company’s own account setup and sign-in systems.
