I am new to MOE. I have not seen any documents / examples, etc. about how to authenticate a cross platform app. I have been able to access SQLite from both Android and IOS. I set up a Google Sign in for Android which gives me a token I can validate on my web services. I do not know how to implement a similar login / token validation for IOS. Do I do this natively (I believe IOS does thumb print or iTunes PW), but I am not sure if I write the code in Java, and if there is possibly an example I could view would be helpful.
Sorry if this is a duplicate post, I have not seen anything on the web about authentication (and MOE).
