I use only OAuth login in my app. I get usernames using API with
#onCreateUser function. The usernames retrieved from API can be the same. My users collection grew recently and I get username duplication error more often. I don’t use usernames to anything more than showing it in few places in my app. What is the best solution to this problem? The easiest one I’ve been thought is changing username field to something like steamUsername, but maybe there is better solution.
Thanks in advance
