My team has been wondering: We allow third-party login via one OAuth provider (Esri) in addition to "local" accounts. Users who log in with Esri do so to access content in their Esri account, not as a matter of convenience. Apple's guidelines stipulate that it will be "required as an option for users in apps that support third-party sign-in". In contrast with social logins, you cannot create an account with our app via the Esri login, and your Esri account must be set up first in the back-end to even use it at all. We can't think of a way to feasibly support this per their requirements, unless Esri allows it via their OAuth flow as well (they do support Facebook/Google today).
