I have a mobile app which will only use a Unique Code for users to login. How can i authenticate using Firebase or AWS Cognito or any other cloud providers? The screen looks like below :
Should i end up writing a custom Authentication WebService for this and will Apple iTunesConnect review and approve my app without a username, pwd and email address?
In terms of the first question:
How can i authenticate using Firebase or AWS Cognito or any other cloud providers?
According to your request, I think it's more of a login "passcode" than traditional authentication. So user should get this code from the app developer. If that's the case, then simply insert some data into the Firebase and call the query for the passcode entered on the client side.
The second one: Check the App Store Review: https://developer.apple.com/app-store/review/guidelines/
Make sure your app has been tested on-device for bugs and stability before you submit it, and include demo account info (and turn on your back-end service!) if your app includes a login.
I think apple doesn't take the authentication as a necessary step(After all the are tons of tool-apps out there on the app store without any account involved, I personally even have 2 apps on the app store without authentication :p ). But in order to let them test your app, you need to provide the passcode(even with detailed explanation on how to use the passcode if necessary)
Hope this could be helpful.
