We recently are adding apple signup in our app and in our db we have 50 chars as max length of user identifiers. i was wondering how long they can be on apple and whether we should tweak the max length on our side.
Max length of user identifier
Does someone have the answer?
I used to get a user identifier from Apple that their max length was under 50 chars. in the past few months, I have gotten a small amount of user identifiers that are bigger than 50. is it fraud or valid users?
