Hi,
I’m building this game which has a log in framework with it for multiple users. But i’d like to know what you guys use for user management? I’m thinking about using an SQL Database, but i don’t know if that’s the best solution.
Thx!
Anyone?
What do you want people to say? SQL is a database and not really related to login. Obviously you can use a SQL database running on a web server somewhere and store usernames and passwords and authenticate people through REST access to the server. I’m guessing most iOS developers around here use Game Center.
I think this is what you are searching for,
check this link:- Unity Developers Home
And then click User-Service.
gud luck 
happy coding…
